Answer:
Hence, the value of expression (2) is ⇒ 1.08.
Step-by-step explanation:
We are given a fact such that:
4.86 : 0.45=10.8 ------(1)
Now we are asked to find the value of the mathematical expression:
4.86 : 4.5 --------(2) without actually dividing.
We could clearly see that the numerator in both the mathematical expression is same only there is a difference in there denominator.
The denominator in second expression is just a multiplication of the denominator of first expression by 10.
Hence we divide both side of expression (1) by 10 to obtain the expression (2).
i.e. 4.86: (0.45×10)=10.8:10
i.e. 4.86: 4.5= 1.08
Hence, the value of expression (2) is 1.08.
