4 and 3 / 5 times 9 / 7 minus 3 / 5 divided by 1 / 7 / 2

4 and 3 / 5 times 9 / 7 minus 3 / 5 divided by 1 / 7 / 2

4 and 3 / 5 × 7 / 9-3 and 1 / 5 △ 1 and 2 / 7
=23/5×7/9-16/5÷9/7
=161/45-112/45
=49/45

If number a is divided by number B, the quotient is 39 and the remainder is 15. If number a is divided by 0.1 and number B is multiplied by 10, what is the quotient and the remainder?

39,15

Number a is twice that of number B. what is the quotient of number a divided by number B

The number a is twice the number B. the quotient of the number a divided by the number B is 2

The number a is 13 times the number B. the quotient of the number a divided by the number B is () if the number a is reduced by 5 times, the quotient of the number B will not change

The quotient is 13. The B number should also be reduced by five times

______ And 0.125 are reciprocal; a divided by B, the quotient is exactly the reciprocal of B, a is______ ．

8 and 0.125 are reciprocal; number a = number B × reciprocal of number b = 1

Number a is seven times that of number B. what is the quotient of number a divided by number B

7

If the number a is divided by the number B, the quotient is 1 / 3. If the number a is increased by 7, the quotient is 2 / 5. Which number a is ()

Let a be x and B be y
x/y=1/3
(x+7)/y=2/5
You can solve the equations
Remember to adopt!

64 / 2-13 / 26 / 9-2 / 3

64 / 2-13 / 26 / 9-2 / 3
=64 out of 2-13 x 26 out of 9-2 out of 3
=128 of 2-9-2 of 3
=128 / 2-3 / 2-9
=4 / 3-128 / 9
=12 / 9-128 / 9
=-116 out of 9

(2.3 cycles - 6 / 13 / 9 / 26-2 / 3) * 1.5

The original formula = [7 / 3 - (6 / 13) × (26 / 9) - 2 / 3] × (3 / 2) = (7 / 3-4 / 3-2 / 3) × (3 / 2) = 1 / 2

Who's bigger, 4 out of 13, 9 out of 26 and 11 out of 52

4/13=16/52,
9/26=18/52
11/52
