Question

1)24×8=a×4. 2)120×2=60×b. 3)90×6=c×3. 4)80×8=d×4

Answer 1

1) 192=4a
a=48
2) 240=60b
b=4
3) 540=3c
c=180
4) 640=4d
d=160

Answer 2

Let's solve each of the equations step by step:

1. 24 × 8 = a × 4

We can simplify the equation by dividing both sides by 4: (24 × 8) ÷ 4 = a

Simplifying the left side: 192 ÷ 4 = a

Therefore, a = 48.

2. 120 × 2 = 60 × b

Again, we simplify by dividing both sides by 60: (120 × 2) ÷ 60 = b

Simplifying the left side: 240 ÷ 60 = b

Thus, b = 4.

3. 90 × 6 = c × 3

We divide both sides by 3 to simplify: (90 × 6) ÷ 3 = c

Simplifying the left side: 540 ÷ 3 = c

Hence, c = 180.

4. 80 × 8 = d × 4

Dividing both sides by 4 yields: (80 × 8) ÷ 4 = d

Simplifying the left side: 640 ÷ 4 = d

Therefore, d = 160.

To summarize the solutions: a = 48 b = 4 c = 180 d = 160
