Question

A)3/4+3/20 Б)7/10+3/20 В)2/7+4/35 Г)21/32+1/8

Answer 1

15+3/20=9/10
14+3/20=17/20
10+4/35=14/35
21+4/32=25/32

Answer 2

A) 3/4 + 3/20 To add these fractions, we need to find a common denominator. The least common multiple of 4 and 20 is 20. So, we can rewrite the fractions with the common denominator: 3/4 = 15/20 3/20 = 3/20 Now we can add them together: 15/20 + 3/20 = 18/20 Then we can simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 2: 18/20 = 9/10

B) 7/10 + 3/20 Again, we need to find a common denominator, which is 20. So, we can rewrite the fractions with the common denominator: 7/10 = 14/20 3/20 = 3/20 Now we can add them together: 14/20 + 3/20 = 17/20

C) 2/7 + 4/35 To add these fractions, we need to find a common denominator. The least common multiple of 7 and 35 is 35. So, we can rewrite the fractions with the common denominator: 2/7 = 10/35 4/35 = 4/35 Now we can add them together: 10/35 + 4/35 = 14/35 Then we can simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 7: 14/35 = 2/5

D) 21/32 + 1/8 To add these fractions, we need to find a common denominator
