Patel squeezed oranges so that his family could have fresh-squeezed juice for breakfast. He squeezed StartFraction 4 over 17 End

lord [1]

Answer:

3089/11220

Approximately = 0.2753

Step-by-step explanation:

Patel estimates that he needs 2 cups of Orange juice.

But let's know the amount he already has.

4/17 + 3/10 + 9/20 + 3/11 + 7/15

= 3/10 + 9/20 + 7/15 + 3/11 + 4/17

=( 18 + 27 + 28)/60 + (51+44)/187

= 73/60 + 95/187

=( 13651 + 5700)/11220

= 19351/11220

= 1(8131/11220)

So to complete it two he needs ( 11220-8131)/11220= 3089/11220

Approximately = 0.2753
