B. Because the divisor, 4.2, has only value in the ones and tenths places, so we only have to multiply by 10 to get to 42, which is the whole number you need.
Answer:
The Answer would be 8.
Step-by-step explanation:
I just did a quiz with this exact question
The value decimal point is changing going to the right as you divide a number by 10.
For example
=> 2000.3 / 10
notice the decimal point
=> 200.013, the value of decimal numbers increases as the value of whole number decreases.Let’s divide again
=> 200.013 / 10
=> 20.0013 , now we already have 4 digits in our decimals.
So, simply as we divide the given number by 10, the decimal point moves to the left making the value of whole number decreases and making the number of digits of decimal increase.
21/36.
All you have to do is multiply numerators by numerators and denominators by denominators. Simplify if needed
