Question

take 40 sweets.split them in to tenths.give 3/10 to your mom, 2/10 to your dad and 20 to your brother or sister .How many do you have left?

Answer 1

Answer:

Zero

Step-by-step explanation:

Each tenth is 40 / 10 = 4 sweets.

3/10 (that is, three tenths) for Mum are then 3 x 4 = 12

2/10 (that is, two tenths) for Dad are 2 x 4 = 8

So far, we've given away 12 + 8 = 20 sweets.

That leaves us with 40 - 20 = 20 sweets.

From these, we give 20 sweets to the brother or sister.  But that's all that we had left!  So we're left with none.
