Multiply 4.6 x 2/7 round the answer to the nearest hundredth

Answers

Answer 1

Answer: type into the calculator:
4.6*(2/7)
the calculator answer is 1.31428...
we want to round to the nearest hundredth. the hundredths place is in bold: 1.31428
to round, we look at the number to the right of the hundredths place, which is underlined:
1.31428
if the number on the right is 5 or greater, we add 1 to the number to the left. if the number on the right is 4 or less, then we leave the number on the left alone.
the number on the right here is 4, so we leave the number on the left alone, leaving us with 1.31

Answer 2

Answer: 4.6x2/7
well I converted 2/7 to its decimal which is 0.285714286
then did 4.6x0.285714286 and got 1.314285716

Use the distributive property:

6f+24 + 2f + 8

Now combine like terms:

8f +32

The answer is 8f + 32

Answer:

8 f + 32

Step-by-step explanation:

6 ( f + 4 ) + 2 ( f + 4 )

Distribute

6 × f + 6 × 4 + 2 × f + 2 × 8

6 f + 24 + 2f + 8

Collect like terms

6 f + 2 f + 24 + 8

Add the numbers

8 f + 32
