a. The exact value is 615079
b. By using approximation to 1 significant figure we get 600000.
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
The expression is given as;
13822 × 623 / 14
Now,
a. Solve the expression as;
13822 × 623 / 14 = 8,611,106 / 14
= 615,079
Thus, The exact value is 615079.
b. Reduce fraction to the lowest term by canceling the greatest common factor:
6911 × 89
Then, Calculate the product = 615079.
So, By using approximation to 1 significant figure we get 600000.
The probable question can be: A} work out exact value of 13822 x 623/14
b} using your approximations to 1 significant figure, check answer a makes sense.
