n200080 [17]

Question Continuation:

Glenn bought 3 pounds of tomatoes. He used 5/8 of them to make sauce.

Make an equation that shows the number of pounds of tomatoes Glenn used for the sauce.

Answer:

$y = \frac{15}{8}\ lb$

Step-by-step explanation:

Given

Weight of Tomato = 3 lb

Used Proportion = 5/8

Required

Determine the portion used

To solve this we simply multiply the used proportion by the weight of the tomato bought

Represent the used portion with y.

So:

$y = Weight * Used\ Proportion$

$y = 3\ lb * \frac{5}{8}$

$y = \frac{15}{8}\ lb$
