Answer :
0.5 x 0.80
= 0.4 for 0.5 pounds of peaches
0.7 x 0.90
= 0.63 for 0.7 pounds of oranges
For peaches, $.80/pound so 0.5 is a half of 1 so you divided it to two and you get: $.80÷2=$.40
For oranges, $.90/pound so you 0.7 is 7/10 of 1 so you multiply $.90 to 7/10 or times $.90 to 0.7 and you get $.63
When you add the total, you get $.40+$.63= $1.03
For oranges, $.90/pound so you 0.7 is 7/10 of 1 so you multiply $.90 to 7/10 or times $.90 to 0.7 and you get $.63
When you add the total, you get $.40+$.63= $1.03
