Answer 1

Ответ:

Пошаговое объяснение:

А) 21/100 : 3 =21/100*1/3=7/100

б) 5/6 : 5 =5/6*1/5=1/6

в) 9/10 : 10 =9/10*1/10=9/100

г) 1/2 : 50=1/2*1/50=1/100

Answer 2

To simplify each of the given fractions, follow these steps:

А) 21/100 : 3 To divide fractions, you can multiply the first fraction by the reciprocal of the second fraction. The reciprocal of 3 is 1/3.

So, (21/100) ÷ 3 = (21/100) * (1/3) = (21 * 1) / (100 * 3) = 21 / 300 = 7 / 100.

б) 5/6 : 5 Again, multiply the first fraction by the reciprocal of the second fraction. The reciprocal of 5 is 1/5.

So, (5/6) ÷ 5 = (5/6) * (1/5) = (5 * 1) / (6 * 5) = 5 / 30 = 1 / 6.

в) 9/10 : 10 Follow the same process:

(9/10) ÷ 10 = (9/10) * (1/10) = (9 * 1) / (10 * 10) = 9 / 100.

г) 1/2 : 50 Once more:

(1/2) ÷ 50 = (1/2) * (1/50) = (1 * 1) / (2 * 50) = 1 / 100.

So, the simplified fractions are:

А) 7/100 б) 1/6 в) 9/100 г) 1/100
