Answer 2

To simplify the given fractions, we need to find the values of the variables (a, c, b, and d). Let's solve each equation step-by-step:

1. 4/a = 16/20

To solve for 'a,' we cross-multiply: 4 * 20 = 16 * a

80 = 16a

Now, divide both sides by 16 to isolate 'a': a = 80 / 16 a = 5

So, the simplified fraction is 4/5.

2. c/8 = 25/40

To solve for 'c,' cross-multiply: c * 40 = 25 * 8

Now, divide both sides by 40 to isolate 'c': c = (25 * 8) / 40 c = 5

So, the simplified fraction is 5/8.

3. 39/27 = b/9

To solve for 'b,' cross-multiply: 39 * 9 = 27 * b

Now, divide both sides by 27 to isolate 'b': b = (39 * 9) / 27 b = 13

So, the simplified fraction is 13/9.

4. 49/32 = 12/d

To solve for 'd,' cross-multiply: 49 * d = 12 * 32

Now, divide both sides by 49 to isolate 'd': d = (12 * 32) / 49

d ≈ 7.79 (rounded to two decimal places)

So, the simplified fraction is 49/32 or approximately 1.53 (rounded to two decimal places).

Simplified fractions:

1. 4/5
2. 5/8
3. 13/9
4. 49/32 (or approximately 1.53)
