If A = { 2,3,5,7 } then find the value of n(A).

We conclude that

Step-by-step explanation:

Given the set

If we closely observe, we can easily identify that set A has 4 elements, which are 2, 3, 5, and 7.

n(A) denotes the number of elements in a set.

Since set A has 4 elements, therefore the value of n(A) = 4

Thus, we conclude that

Its acctualy 1.53

Step-by-step explanation:

First you have to add 2.45+5

wich is 7.45 then divide it by 5

7.45/5

you will get 1.53 so in the end alan will have 1 hole block, 5 tens and 3 ones
