9/10 minis what equals 1/5?

Mathematics
1 answer:
Darya [45]3 years ago
4 0

Answer:

7/10

Step-by-step explanation:

Set up an equation to solve the problem

1/5 = 9/10 - x

Lets make them all have a common denominator

1/5 = 2/10

Subtract the 9/10

 2/10 =  9/10 - x

- 9/10   - 9/10

-7/10 = -x

Since -x equals -7/10, that means positive x equals 7/10

The answer then comes out to:

x = 7/10

6. At a game, there were 24 adults and 10 children. Keeping the same ratio,
irina1246 [14]

Answer:

The total number of adults will be: 120 adults

Step-by-step explanation:

Given that there were 24 adults and 10 children in a game.

Thus, adults to children ration = 24:10 or 24/10

  • If there were 50 children, how many adults would be at the game?

Let 'x' be the number of adults when there 50 children.

so the ration of adults 'x' to 50 childern = x: 50 or x / 50

As the ratio is the same.

Thus,

24 : 10 = x : 50

24/10 = x/50

switching sides

x/50  = 24/10

x  = 24/10 × 50

x = 120 adults

Therefore, the total number of adults will be: 120 adults
