Question

1)3 1/3:2/3*1/5= 2)3 1/5*5/8:2/7= Ответ с решением

Answer 1

Переводим смешанные дроби в неправильные:

1. 10/3 : 2/3 * 1/5 = 1

1) 10/3 : 2/3 = 10/3 * 3/2 = 5/1

2) 5/1 * 1/5 = 1

2. 16/5 * 5/8 : 2/7 = 7

1) 16/5 * 5/8 = 2/1

2) 2/1 : 2/7 = 2/1 * 7/2 = 7

Answer 2

1. To solve this expression, we need to simplify the multiplication of the fractions on the right side first:

2/3 * 1/5 = 2/15

Now we can substitute the simplified fraction into the expression:

3 1/3 : 2/15

Next, we convert the mixed number to an improper fraction:

3 1/3 = (3*3 + 1)/3 = 10/3

Finally, we can divide by a fraction by multiplying by its reciprocal, so we flip the second fraction and multiply:

10/3 * 15/2 = 150/6 = 25

Therefore, the solution is 25.

2. We can start by simplifying the multiplication of fractions:

3 1/5 * 5/8 = (16/5) * (5/8) = 2

Next, we divide by a fraction by multiplying by its reciprocal, so we flip the second fraction and multiply:

2 * 7/2 = 7

Therefore, the solution is 7.
