How to multiply fractions - SSAT Middle Level Quantitative

                     

When we multiply a fraction by a whole number, we first want to make the whole number into a fraction. We do that by putting the whole number over Then we multiply like normal.

Because can go into an even time.

                     

When we multiply a fraction by a whole number, we first want to make the whole number into a fraction. We do that by putting the whole number over Then we multiply like normal.

Because can go into and even times.

By order of operations, perform the rightmost addition (the one within the parentheses) first, the multiplication second. and the leftmost addition last.

Rewrite the mixed fractions as improper fractions, cross-cancel, and multiply across:

By order of operations, multiply first:

Multiply 14 by 16, and position the decimal point so that two digits are right of it:

Now add this product to 6.5:

Append a zero to the 6.5, and align the decimal points:

By order of operations, multiply first:

Multiply 32 by 15, and position the decimal point so that two digits are right of it:

Now add this product to 5.96:

Append a zero to the 4.8, and align the decimal points:

The product of two numbers of unlike sign is the (negative) opposite of the product of their absolute values.

There are a total of two digits to the right of the two decimal points. Therefore, the product can be calculated by multiplying 201 by 203, then placing the decimal point so that there are three digits at right.

Since we need to affix a negative symbol in front, the answer is

When multiplying a fraction, simply multiply straight across - numerator times numerator, denominator times denominator. When you do that, you should get this answer:

Do not forget to reduce. 3 and 30 can both be evenly divided by 3, which would give you as your answer.

One Euro is equivalent to $1.27, so multiply the number of euros - 800 - by this conversion factor.

First, multiply the numbers, ignoring the decimal points:

Since the two factors in the original product have three digits to the right of the decimal points between them, position the decimal point in the product such that three digits are at its right. The result, therefore, is

First, remove the decimal points, multiplying as follows:

Between them, the two factors have five digits to the right of their decimal points, so position the decimal point in the product so that there are five digits to the right. This will require placing a zero in front as a placeholder, so the final result is

Multiply the numerators together, and then multiply the denominators together:

To find the product of two fractions, multiply the numerators together and then multiply the denominators together.

, which can be reduced to .

To find the product of two fractions, multiply the numerators together and then multiply the denominators together.

To solve for this expression, first multiple the numerators, and then multiply the demonators.

Simplify the fraction by removing a common factor.

The identity property of multiplication states that there is a number 1, called the multiplicative identity, that can be multiplied by any number to obtain that number. Of the four statements,

demonstrates this property.

By the order of operations, carry out the operations in parentheses first; since there is a multiplication and a subtraction present, carry them out in that order. Finally, carry out the remaining subtraction:

To raise a negative number to an even-numbered power, raise its absolute value to that power:

By the order of operations, carry out the operation in parentheses, which is the rightmost subtraction, then the multiplication, then the leftmost subtraction:
