Question

4×3/20= 5/11×22/25= 14×7/16=

Answer 1

4*3/20=12/20=0,6 или 6/10

5/11*22/25=2/5 или 0,4

14*7/16=6,125 или 6ц1/8

Answer 2

Let's solve each of these multiplication problems step by step:

1. 4 × 3/20: To multiply a whole number by a fraction, you can multiply the whole number by the numerator (top part of the fraction) and keep the denominator (bottom part of the fraction) the same.

   So, 4 × 3/20 = (4 × 3) / 20 = 12/20.

2. 5/11 × 22/25: To multiply two fractions, multiply the numerators together and the denominators together.

   (5/11) × (22/25) = (5 × 22) / (11 × 25) = 110/275.

3. 14 × 7/16: Again, to multiply a whole number by a fraction, multiply the whole number by the numerator and keep the denominator the same.

   14 × 7/16 = (14 × 7) / 16 = 98/16.

Now, let's simplify these fractions:

1. 12/20: Both 12 and 20 are divisible by 4, so you can simplify this fraction: 12/20 = (12 ÷ 4) / (20 ÷ 4) = 3/5.

2. 110/275: Both 110 and 275 are divisible by 5, so you can simplify this fraction: 110/275 = (110 ÷ 5) / (275 ÷ 5) = 22/55.

3. 98/16: Both 98 and 16 are divisible by 2, so you can simplify this fraction: 98/16 = (98 ÷ 2) / (16 ÷ 2) = 49/8.

So, the simplified results are:

1. 4 × 3/20 = 3/5
2. 5/11 × 22/25 = 22/55
3. 14 × 7/16 = 49/8
