Answer:
70/14=5 and 54/9=6
Explanation:
Your first question is 70 divide by 14 it will be equal to 5
and the second question is 54 divide by 9 and it will be equal to 6
Now lets start solving it one by one with detailed explanation,
Division is nothing but adding one number as many times as other number means, if you want to divide 70 by 14 then you need to add 14 five times
14+14+14+14+14=70
so you need to add it 5 times hence the answer is five.
Also a smarter way to answer this question is you are dividing 70/14
so just think like first multiplying 14 with 10 it will give you 140 but you need 70 just half of it so you need to multiply with 5 doesn't it?
just think by this way it help you calculate the value in easier way.
Also to get the answer in a quicker way just consider the unit digit place,
like we are dividing 70/14 you don't know the table of 14 so how you will do then just consider the unit digit of 14 i.e 4 so now count its table it is easier to count as compared to 14.
so 4*1=4, 4*2=8, 4*3=12, 4*4=16 and 4*5=70.
now in each count just look at the unit place it 1,8,2,6 and 0.
so now here you can get an hint that by 14 with 5 you can get 70 (as the unit digit multiplication is yielding 0)
so by this way you can solve such problem if you find it harder to calculate, just break the bigger problem in smaller parts and then try to solve it.
similarly we can calculate for 2nd question,
we need to add 9 six times to reach 54,
9+9+9+9+9+9= 54
hence the answer is 6.
You can do it for all other questions also.
