Answer:
28 grapes in total
Explanation:
grapes are shared in the ratio 2 : 5 = 2x : 5x ( x is a multiplier )
Eva gets 12 more grapes than Dora , then
5x = 2x + 12 ( subtract 2x from both sides )
3x = 12 ( divide both sides by 3 )
x = 4
total grapes = 2x + 5x = 7x = 7 × 4 = 28
Eva gets 5x = 5 × 4 = 20
Dora gets 2x = 2 × 4 = 8
that is Eva gets 12 more than Dora
