Jasmine bought 30 kiwi fruit for $10. How many kiwi can Lisa buy if she has $4?

8 kiwi

Step-by-step explanation:

This is a typical proportional problem for Algebra.

You can do this problem several ways, some shorter than others, however, I want you to understand. So, with that said,

You place the following equation together:

Number of Kiwi/Dollars = Number of Kiwi/Dollars

You are given three of the values:

32 Kiwi/16 = x/4   Please notice: You know Jasmine bought 32 Kiwi for $16.00 and know she has $4.00. You do not know how many kiwi she can purchase. Do you see this?

Now, since this is an equation (an equal sign between two fractions) you can cross-multiply. When you do so you multiply the numerator on the left with the denominator on the right. Then cross-multiply the denominator from the left with the numerator on the right.

You are left with the following due to cross multiplication:

16 x = 4 (32) or 128

16x = 128  Solve for x by dividing 16 into 128 and you arrive at 8

WHY I do this problem in this manner is because you can ALWAYS check your work. In other words, plug 8 (the value for x) into the original equation. When you do so watch what happens:

Original equation: 32/16 = x/4

Then:

32/16 = x/4  or 32/16 = 8/4

Cross multiply: Does 32 times 4 equal 16 times 8?  Yes, it indeed does.

do you have the measurements?
