Question

Q. No. 6 & 7. Step by step solution.

Answer 1

Answer: The answer of question number 6 is 5/12.

The answer of the question number 7 is -2/8.

Step-by-step explanation: For the question number 6

We have to divide the numerator and denominator by 18 to get 5 in numerator because 90/5=18.

=> 90/215 = 5/12.

For the question number 7

We have to divide the numerator and denominator by 32 to get 8 in denominator because. 256/8=32.

=>-64/256 = -2/8.

Answer 2

(6) The rational number is $\frac{5}{12}$ for the given term $\frac{90}{216}$

(7) The rational number for the given term $\frac{-64}{256}$ is $\frac{-2}{8}$

Step-by-step explanation:

Given data

Find the rational number for the following

(6) $\frac{90}{216}$ (with numerator 5)

(7) $\frac{-64}{256}$ (with denominator 8)

(6) In $\frac{90}{216}$ , we have to get numerator as 5, so we can divide 90 by 5 to check whether it is possible or not.

$\frac{90}{5} = 18$ (possible)

Now divide 216 with 18, $\frac{216}{18} = 12$ (possible)

(90 = 5 × 18) (216 = 12 × 18)

Therefore the expression $\frac{90}{216}$ can be written in rational number as $\frac{5}{12}$ wiith numerator '5'

(7)  In $\frac{-64}{256}$  , we have to get denominator as 12, so we can divide 216 by 8 to check whether it is possible or not.

$\frac{256}{8} = 32$ (possible)

Now divide 64 with 32, $\frac{64}{32} = 2$ (possible)

(-64 = -2 × 32) (256 = 8 × 32)

Therefore the expression $\frac{-64}{256}$ can be written in rational number as $\frac{-2}{8}$ with denominator '8'
