Question

Запишите каждую из дробей 5/15 , 11/25 , a/3 , b/5 в виде дроби со знаменателем: 1)900; 2)1350; 3)2700. Числитель и знаменатель какой дроби умножили на наименьшее число

Answer 1

1) 900:15=60     5*60 \15*60=300\900
  900:25=36      11*36 \ 25*36=  396\900
 900:3=300        а*300 \ 3*300= 300а \900
 900:5=180        в*180 \ 5*180= 180в \ 900

2) 1350:15=90       5*90 \ 15*90= 450\1350
    1350:25= 54      11*54 \ 25*54= 594\1350
     1350:3= 450     а*450 \ 3*450= 450а\1350
     1350:5= 270     в*270 \ 5*270=270в\1350


3)  2700:15=180       5*180 \ 15*180= 900\2700
     2700:25= 108      11*108 \ 25*108= 1188\2700
     2700:3=900          а*900 \ 3*900=900а\2700
    2700:5= 540          в* 540 \ 5*540= 540в \ 2700

на наименьшее число умножали  числитель и знаменатель дроби 11\25

Answer 2

Converting Fractions to Fractions with Specific Denominators

To convert the fractions 5/15, 11/25, a/3, and b/5 to fractions with denominators of 900, 1350, and 2700, we need to find the least common multiple (LCM) of the original denominators and then multiply both the numerator and denominator of each fraction by the appropriate factor.

Let's go through each fraction one by one:

1. 5/15: - The original denominator is 15. - The LCM of 15 and 900 is 900. - To convert the fraction to have a denominator of 900, we need to multiply both the numerator and denominator by 60 (900 ÷ 15). - The resulting fraction is 300/900.

2. 11/25: - The original denominator is 25. - The LCM of 25 and 1350 is 1350. - To convert the fraction to have a denominator of 1350, we need to multiply both the numerator and denominator by 54 (1350 ÷ 25). - The resulting fraction is 594/1350.

3. a/3: - The original denominator is 3. - Since the denominator is a variable, we cannot determine the exact conversion without knowing the value of a. - However, we can still express the converted fraction with a denominator of 2700 as (900a)/2700.

4. b/5: - The original denominator is 5. - Since the denominator is a variable, we cannot determine the exact conversion without knowing the value of b. - However, we can still express the converted fraction with a denominator of 2700 as (540b)/1350.

To summarize,
