Possible Answers:

\dpi{100} 34-20

\dpi{100} 34\div 20

\dpi{100} 34\times 20

\dpi{100} 34+20

Example Question #31 : Isee Lower Level (Grades 5 6) Quantitative Reasoning

If Lisa has \dpi{100} b boxes of pens, and each box contains 12 pens, which expression would tell us how many pens that Lisa has?

Possible Answers:

\dpi{100} b-12

\dpi{100} b\div 12

\dpi{100} b\times 12

\dpi{100} b+12

Correct answer:

\dpi{100} b\times 12

Explanation:

Every box of pens represents 12 total pens.  So if we have 3 boxes, we have\dpi{100} \dpi{100} 12+12+12=36\ pens

which is the same as saying \dpi{100} 3\times 12=36\ pens.

Here, since we only know that Lisa has \dpi{100} b boxes of pens, so we would multiply that by the 12 pens in each box.
