class 7 question

fraction and decimal ch 2​

Answer 1

HEY HERE'S YOUR ANSWER

FIRST WE MUST SEE THE LCM OF ALL THE DENOMINATOR

(i) 1/9, 2/5, 3,4

LCM = 2×2×3×3×5 = 180

1/9 × 20/20 = 20/180

2/5 × 36/36 = 72/180

3/4 × 45/45 = 135/180

IN ASCENDING ORDER - 20/180(1/9), 72/180(2/5), 135/180(3/4)

(ii) 2/7, 11/35, 9/14, 13/28

LCM = 2×2×5×7 = 140

2/7 × 20/20 = 40/140

11/35 × 4/4 = 44/140

9/14 × 10/10 = 90/140

13/28 × 5/5 = 65/140

IN ASCENDING ORDER - 40/140(2/7), 44/140(11/35), 65/140(13/28), 90/140(9/14)

HOPE IT HELPS YOU :)

Answer 2

$(i) \frac{1}{9},\frac{2}{5},\frac{3}{4}$

One way is to divide these numbers and then arrange them.

$\frac{1}{9}= 0.111\\\\\frac{2}{5}=0.4\\\\\frac{3}{4}=0.75\\\\0.1,0.4,0.75$

and the second way is to make denominators of all three equal...

$\frac{1*20}{9*20}, \frac{2*36}{5*36}, \frac{3*45}{4*45}\\\\\\\frac{20}{180},\frac{72}{180},\frac{135}{180}$

Now denominators are equal, now you can arrange them(arrange them by checking the numerators.

$\frac{20}{180}, \frac{72}{180}, \frac{135}{180}$

Now, how to make denominators equal.

find LCM of denominators

like in that question, LCM of 9,5,4 is 180

this means you have to make all the denominators 180 by multiplying with specific numbers.

(Note :- multiply numerator and denomination with same numbers).

Do the second one

Ask me on comments if you didn't get the second one..
