When a number is multiplied by a fraction equal to 1, the value of the number remains the same.

Using this, we can find the values:-

Image 2 answers :

When we cancel the same 4 of LHS remaining we get as 4/5. By doing the same method, we can find the remaining answers.

Image 1 answers :

Here, cancel the common numbers in LHS and write back the remaining uncancelled numbers to get 4/3 in RHS.

Using same method,

Next, Now in last two questions, we have to do a little differently. Till this much time we did by cancelling the common numbers. So, multiply the numerator and denominator.

So, above question's answer is 3/8.

Likewise, using the same method, find the next question :-

So, next answer is 8/15.

Hope this Helps...

step-by-step explanation:

a. 12.5 kg

step-by-step explanation:

f = ma

so
