Question

7 1\2×2 4\15 5 1\6×3 1\7 3 3\7×2 1\3 7 1\3×2 2\11

Answer 1

1) 15*34/15=510/15=34
2) 31/6*22/7=341/21=16 5/12
3) 24/7*7/3=8
4) 22/3*24/11=16

Answer 2

To solve this expression, let's first convert all the mixed fractions into improper fractions and then perform the multiplication:

7 1/2 = (2 * 7 + 1)/2 = 15/2 5 1/6 = (6 * 5 + 1)/6 = 31/6 3 3/7 = (7 * 3 + 3)/7 = 24/7 7 1/3 = (3 * 7 + 1)/3 = 22/3

Now, let's perform the multiplication:

(15/2) × (31/6) × (24/7) × (22/3)

To multiply fractions, we simply multiply the numerators together and the denominators together:

Numerator = 15 × 31 × 24 × 22 = 450240 Denominator = 2 × 6 × 7 × 3 = 252

So, the result of the expression is:

450240/252

Now, let's simplify this fraction:

Divide the numerator and denominator by their greatest common divisor (GCD) to simplify the fraction:

GCD(450240, 252) = 84

450240 ÷ 84 = 5360 252 ÷ 84 = 3

The simplified fraction is:

5360/3

Therefore, the result of the expression is 5360/3.
