Arecipe calls for 3/4 cup of butter. angie wants to triple the recipe, but she has only 1 5/8.
how much butter must she borrow from a neighbor?

So tripple of 3/4 is 3/4 times 3/1=9/4=2 and 1/4
she has 1 and 5/8
compare 1 and 5/8 and 2 and 1/4

convert 1/4 to 2/8

she has 1 and 5/8 but she needs 2 and 2/8
1=8/8
1 and 5/8 and needs 1 and 10/8
1 and 5/8+x=1 and 10/8
subtract 1
5/8+x=10/8
subtrarct 5/8
x=5/8
she must borrow 5/8 cups from neighbor

The answer of the above is

It’s 24.6 after you round to the nearest tenths the answer should be 25.0
