Answer:
Therefore, the simplified answers are:
1. 9/25
2. 4/9
3. 1/8
4. 2/3
5. 1/5
6. 3/22
Explanation:
To simplify each of these multiplication problems, we can follow these steps:
1. Multiply the numerators (top numbers) together.
2. Multiply the denominators (bottom numbers) together.
3. Simplify the resulting fraction, if possible, by finding the greatest common divisor (GCD) of the numerator and denominator and dividing both by it.
Let's solve each problem:
1. (9/20) x (4/5)
Numerator: 9 x 4 = 36
Denominator: 20 x 5 = 100
Simplify: 36/100 = 9/25
2. (8/15) x (5/6)
Numerator: 8 x 5 = 40
Denominator: 15 x 6 = 90
Simplify: 40/90 = 4/9
3. (7/12) x (3/14)
Numerator: 7 x 3 = 21
Denominator: 12 x 14 = 168
Simplify: 21/168 = 1/8
4. (7/10) x (20/21)
Numerator: 7 x 20 = 140
Denominator: 10 x 21 = 210
Simplify: 140/210 = 2/3
5. (8/18) x (9/20)
Numerator: 8 x 9 = 72
Denominator: 18 x 20 = 360
Simplify: 72/360 = 1/5
6. (3/8) x (4/11)
Numerator: 3 x 4 = 12
Denominator: 8 x 11 = 88
Simplify: 12/88 = 3/22
Therefore, the simplified answers are:
1. 9/25
2. 4/9
3. 1/8
4. 2/3
5. 1/5
6. 3/22
