Question

Rajesh bought a Math book for rupees 25*1/2 and a science book for rupees 20*1/4 . how much money did he spend​

Answer 1

cost of maths book is 25*1/5=₹12.5

cost of science book is 20*1/4=₹5

total money spend =12.5+5=₹17.5

Answer 2

Answer:

So we need to find total cost so add both of them

Step-by-step explanation:

25*1/2 + 20*1/4 = 25/2 + 20/4

so LCM is 4

25*2/2*2 + 20*1/4*1

50/4 + 20/4

70/4 = 17.5 or 17*1/2
