Consider the expression 40+24 Find the greatest common factor of the two numbers and rewrite the expression using the distributi
Natalka [10]

Answer:

Greatest Common Factor of 40+24 is 8

Rewriting the expression using the distributive property we get             8(5+3) =8(5)+8(3)

Step-by-step explanation:

We need to F=find the greatest common factor of the two numbers 40+24 and rewrite the expression using the distributive property

  • Greatest Common Factor:

The greatest number that is divisible by both numbers is known as greatest common factor.

So, Greatest Common Factor of 40+24 is 8

Now, Taking 8 common we get: 8(5+3)

  • Distributive property:

It is written as: a(b+c) = ab+ac

So, we have 8(5+3) =8(5)+8(3)

Rewriting the expression using the distributive property we get 8(5+3) =8(5)+8(3)

98/99

Step-by-step explanation:

0.98 (both the 9 and 8 repeat)

0.98 (both \:  the  \: 9  \: and  \: 8  \: repeat) =  0.\overline{98}   \\ let \: x = 0.\overline{98}...(1) \\ multiply \: both \: side \: of \: eq \: (1) \: by \: 100 \\ 100x = 98.\overline{98}...(2) \\ equation \: (2) - equation \: (1) \\ 100x - x = 98.\overline{98} - 0.\overline{98} \\ 99x = 98 \\ x =  \frac{98}{99}  \\   \implies  \huge \red{0.\overline{98}} =  \orange{\frac{98}{99}}
