Question

Ребят помогите пожалуйста !! 1)5 целых 5/22-1 целую 13/22 2)1 целая 3/5 * 3 целых 1/8 3) 4 целые 1/4+ 2 целые 9/10 Спасибо !!!

Answer 1

1) 
5 5/22 - 1 13/22 = (5 - 1) + (5/22 - 13/22) =
= 4 - 8/22 = 3 22/22 - 8/22 = 3 14/22 = 3 7/11 ,

2)
1 3/5 * 3 1/8 = 8/5 * 25/8 = 25/5 = 5,

3) 
4 1/4 + 2 9/10 = (4 + 2) + (1/4 + 9/10) =
= 6 + (5/20 + 18/20) = 6 + 23/20 = 6 + 1 3/20 = 7 3/20

Answer 2

Calculation 1: 5 целых 5/22 - 1 целая 13/22

To calculate the expression "5 целых 5/22 - 1 целая 13/22," we need to subtract the second quantity from the first.

First, let's convert the mixed numbers to improper fractions: - 5 целых 5/22 = (5 * 22 + 5)/22 = 115/22 - 1 целая 13/22 = (1 * 22 + 13)/22 = 35/22

Now, we can subtract the second quantity from the first: 115/22 - 35/22 = (115 - 35)/22 = 80/22

The result is 80/22.

Calculation 2: 1 целая 3/5 * 3 целых 1/8

To calculate the expression "1 целая 3/5 * 3 целых 1/8," we need to multiply the two quantities.

First, let's convert the mixed numbers to improper fractions: - 1 целая 3/5 = (1 * 5 + 3)/5 = 8/5 - 3 целых 1/8 = (3 * 8 + 1)/8 = 25/8

Now, we can multiply the two fractions: (8/5) * (25/8) = (8 * 25)/(5 * 8) = 200/40

To simplify the fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 40: 200/40 = (200 ÷ 40)/(40 ÷ 40) = 5/1

The result is 5.

Calculation 3: 4 целых 1/4 + 2 целых 9/10

To calculate the expression "4 целых 1/4 + 2 целых 9/10," we need to add the two quantities.

First, let's convert the mixed numbers to improper fractions: - 4 целых 1/4 = (4 * 4 + 1)/4 = 17/4 - 2 целых 9/10 = (2 * 10 + 9)/10 = 29/10

Now, we can add the two fractions: 17/4 + 29/10

To add fractions with different denominators, we need to find a common denominator. In this case, the least common multiple (LCM) of 4 and 10 is 20.

Converting the fractions to have a common denominator of 20: (17/4) * (5/5) = 85/20 (29/10) * (2/2) = 58/20

Now, we can add the fractions: 85/20 + 58/20 = (85 + 58)/20 = 143/20

The result is 143/20.

I hope this helps! Let me know if you have any further questions.
