Question

Sally paid $1.89 for 5 plums. About how many plums would she get for $10?

Answer 1

1.89 ÷ 5 = 0.378
0.378 = Unit Rate
0.378 x 10 = $3.78
----------------------

$1.89 x 2 = $3.78 ✓

Answer 2

set up a ratio and proportion and then cross multiply

5 plums = $1.89
x plums = $10.00

then cross multiply

5*10 = 50

then divide by 1.89

gives you 26.4 .. you cant buy a fraction of a plum... so answer is 26

Answer 3

@BeatriceM2012 after getting 0.378 as cost per unit price, divide 10 by that number to find out the amount of plums you can get
