Step-by-step explanation:
In the first question we will use the division of decimal numbers.
To divide decimal numbers: Multiply the divisor by as many 10's as necessary until we get a whole number. Remember to multiply the dividend by the same number of 10's.
So therefore
17.6/6.2*10/10
176/62
2.838
In the next question we will use multiplicatiin of decimals.
To multiply decimals, first multiply as if there is no decimal. Next, count the number of digits after the decimal in each factor. Finally, put the same number of digits behind the decimal in the product.
So therefore
9.02*4.65
419430/10000
41.9430
Recall that in the problem x÷y=z , also written
yzx
x is called the dividend , y is the divisor , and z is the quotient .
Step 1: Estimate the answer by rounding . You'll use this estimate to check your answer later.
Step 2: If the divisor is not a whole number, then move the decimal place n places to the right to make it a whole number. Then move the decimal place in the dividend the same number of places to the right (adding some extra zeros if necessary.)
Step 3: Divide as usual. If the divisor doesn't go in evenly, add zeros to the right of the dividend and keep dividing until you get a 0 remainder, or until a repeating pattern shows up.
Step 4: Put the decimal point in the quotient directly above where the decimal point now is in the dividend.
Step 5: Check your answer against your estimate to see if it's reasonable.
That is how we can do it by estimating
I really hope it helps you.
