Josh has 4 boxes of candy to share with his 20 classmates. If each classmate receives the same amount of candy, how much candy should each classmate get? Your answer​

Answers

Each classmate would get 1/5 of a box.

Answer:

1/5 of a box of candy

Step-by-step explanation:

Because John has 4 boxes of candy, he needs to divide this by his 20 classmates. So we have 4/20, which reduces to 1/5. So each classmate would get 1/5 of a box of candy (assuming that Josh himself does not get any candy).

how does 9+10 equal 21?​

Answers

9 + 10 does not equal 21.

If you add 9 and 10, you will get 19.

If you are referring to the meme, ok.

The required, left side of the expression 9 + 10 does not equal the right side expression 21.

The correct sum of 9 + 10 is 19. The statement "9 + 10 equals 21" is given by:
Consider the left side of the expression:
= 9 + 10
= 19

Where the right-hand side of the expression is 21, which implies
The left-hand side is not equal to the right-hand side.

However, mathematically, the sum is indeed 19.
