The product of the reciprocal of a and B is equal to the reciprocal of a multiplied by B

The product of the reciprocal of a and B is equal to the reciprocal of a multiplied by B

No, because a * 1 / b = A / B, and the reciprocal of a * B is 1 / A * B, so it's not right

What multiplied by 11 / 4 equals 0.9 plus what equals 1.25 minus what equals 1

(4 / 11) × 11 / 4 = 0.9 + (0.1) = (5 / 7) △ 5 / 7 = 1.25 - (0.25) = 1

1 / 4 of a is equal to 1 / 3 of B, 1 / 8 of a is equal to 7, what is B?

A = 7 △ 1 / 8 = 56
B = 56 × 1 / 4 △ 1 / 3 = 42

3 / 5 of the number a is equal to 7 / 8 of the number B. how many parts of the number a is the number B?
There are 56 students in class 1 of grade 6, of which 3 / 7 are boys. After several boys are transferred, the number of boys accounts for 7 / 15 of the total number of the class, and several boys are transferred

The number a is the number B: 7 / 8 △ 3 / 5 = 7 / 8 × 5 / 3 = 35 / 24
Let's turn in X boys
56×3/7+x=(56+x)×7/15
24+x=(56+x)×7/15
15(24+x)=7(56+x)
360+15x=392+7x
15x-7x=392-360
8x=32
x=4
That is: four boys

What is the sum of a number and three fourths multiplied by five eighths equals twenty-three fourths?

23/24÷5/8-3/4
=23/24×8/5-3/4
=23/15-3/4
=92/60-45/60
=47/60

How much is 120 times 5 / 8 times 3 / 5?

What's 5 out of 8 times 2 out of 7 plus 5 out of 7 times 5 out of 8

=5/8(2/7+5/7)
=5/8

What's 27 out of 50 times 2

If you multiply by molecules, you can divide by 25, which is 27 out of 25

(x plus 3 / 4) multiply by 20 equals 27. How much does x equal?

(x+3/4)*20=27
20x+15=27
20x=12
x=12/20
x=3/5

How much is three fifths multiplied by 27?

3/5x27=81/5
