O b. 2/10
O
c. 5/10
O d. 3/10​

Answer 1

Answer:

C. 5/10

Step-by-step explanation:

Total balls - 10

Red balls - 5

Therefor fraction of red balls are - 5/10

Answer 2

Answer:

Given:

A bag in which:

1. Number of red balls = 5
2. Number of green balls = 3
3. Number of blue balls = 2

To find: The fraction of red balls in the bag

Proof:

According to the question, total number of balls in the bag

= No. of (red balls+ green balls +blue balls)

= 5+3+2

= 5+5

= 10 balls

∴ There are total 10 balls in the bag.

Now,

1. No. of red balls = 5
2. Total balls = 10

∴ Fraction of red balls

= $\frac{ No. of red balls}{Total No. of balls}$

= $\frac{5}{10}$   OR  $\frac{1}{2}$

Hence, the fraction of red balls in the bag

= (c)  $\frac{5}{10}$

Hence, Proved.

Hope you got that.

Thank You.
