Image it like a pizza
The whole pizza is 40 calories and cut into 8 slices. 1 slice has 5 calories. If you ate 7 pizzas out of the eight, how many calories would you consume. therefore 7x5= 35
so 7/8x40=35
It would be 3/17 hope this helped and hope it's right
Answer:
45
135
Step-by-step explanation:
x-y = 90
x = 3y
3y - y = 90
2y = 90
y = 45
x = 3×45 = 135
