arrange the following fraction in descending order. 1) 2 upon 3, 3 upon 5, 7 upon 10, 8 upon 15 tell me answer in method and in full solution
Answers
Answer:
2÷3, 3÷5, 7÷10, 8÷15
take Lcm of denominators 3, 5, 10, 15
Lcm = 5×3×2×3 = 90
take the Lcm as denominator
= 60÷90, 54÷90, 63÷90, 48÷90
now comparing these fractions we get
= 63÷90>60÷90>54÷99>48÷90
= 7÷10>2÷3>3÷5>8÷15 (descending order)
Answer:
Lcm=30
2/3*10/10, 3/5*6/6, 7/10*3/3, 8/15*2/2
20/30, 18/30, 21/30, 16/30
Decending Order..... 21/30 > 20/30 > 18/30 > 16/30
= 7/10 > 2/3 > 3/5 > 8/15......
Step-by-step explanation:
1. Firstly take lcm of denominators.
2. Make the denominators same by multiplying the denominator with that number which can make ur denominator 30
For eg.... 2/3=. 2/3*10/10
Jonse number k saath aap denominator ko multiply kroge, usi no. K saath aap numerator ko bhi multiply kroge....
3. Jb aapke denominators same ho jaaye to numerator ko descending order me set krlo..
4. Then aap un numbers ko likho jis order me aapne decending order me likha hai..... U cn see above fr bttr understanding......
Hope it helps... Plzz mark as brainlist answer..... Nd follow me.....
