1

A recipe shows $2/5$ of a cup of sugar. Choose the correct decimal form of $2/5$. (Divide $2\div5$.)

$0.25$

$0.04$

$4.0$

$0.4$

Explanation

This question tests SSAT Middle Level students' ability to convert between fractions, decimals, and percents. Conversion between these forms is a fundamental math skill where students learn that fractions, decimals, and percents are different ways of representing the same value. For example, the fraction 1/2 is equivalent to the decimal 0.5 and the percent 50%. The correct answer works because it accurately reflects this equivalence, showing an understanding of how to convert the fraction 2/5 to the decimal 0.4 by dividing 2 by 5. A common distractor might mislead students who confuse division, such as interpreting 2/5 as 0.25. To help students master this skill, teachers can provide practice problems that emphasize the relationships between these forms and encourage the use of visual aids like pie charts. Remind students to double-check their work for common errors such as misplacing decimal points or confusing fractions with their reciprocals.

Explanation

This question tests SSAT Middle Level students' ability to convert between fractions, decimals, and percents. Conversion between these forms is a fundamental math skill where students learn that fractions, decimals, and percents are different ways of representing the same value. For example, the fraction 1/2 is equivalent to the decimal 0.5 and the percent 50%. The correct answer works because it accurately reflects this equivalence, showing an understanding of how to convert the fraction 1/2 to 50% via the decimal 0.5. A common distractor might mislead students who confuse the conversion, such as thinking 1/2 is 5% instead of 50%. To help students master this skill, teachers can provide practice problems that emphasize the relationships between these forms and encourage the use of visual aids like pie charts. Remind students to double-check their work for common errors such as misplacing decimal points or confusing fractions with their reciprocals.
