Rewrite the expression c + 0.25c using fractions instead of decimal numbers.
gogolik [260]

Answer:

\huge\boxed{\frac{5c}{4},\ or\ c+\frac{1}{4}c,\ or\ c+\frac{c}{4}}

Step-by-step explanation:

The decimal 0.25 can simply be converted into a fraction by putting it over 100.  

0.25 = \frac{25}{100}

Then, simply divide both the numerator and denominator by 25 to get

\frac{25/25}{100/25}, or \frac{1}{4}

Hope it helps :)

HELPPPPPPPPP i have the most trouble with math what’s the answer??
kiruha [24]

Answer:

option B

3

Step-by-step explanation:

Given in the question an expression

\sqrt\frac{48}{x}

Whole numbers are positive numbers, including zero, without any decimal or fractional parts.

Possible range of domain will be 1 ≤ x ≤ 48

We know that perfect square between 1 and 48 are

1 , 4 , 16 , 25 , 36

1)

x = 3

√48/3 = √16 = 4

2)

x = 12

√48/12 = √4 = 2

3)

x = 48

√48/48 = √1 = 1
