Question

The fish in the pond below, carry some numbers. Choose any 4 pairs and carry out four multiplications with those numbers. Now, choose four other pairs and carry out divisions with these numbers. 

For example,

1. (–13) × (–15) = 195
2. (–24) ÷ 9 = `(-24)/9 = (-8)/3`

Answer 1

1. The four such multiplications are

1. (−27) × (−15) = 405
2. (+41) × (+13) = 533
3. (−28) × (−8) = 224
4. (−37) × (+12) = −444

2. The four such division are

1. (−24) ÷ (+9) = `-24/9 = -8/3`
2. (−13) ÷ (−15) = `13/15​`
3. (+41) ÷ (−27) = `-41/27`
4. (+12) ÷ (−18) = `-12/18 = -2/3`
