139/8 = 17.375 (this is rounded)
135/7 = 19.286 (this is rounded)

so he rode farther on Sunday

135/7 - 139/8 = 107/56 or 1 51/56 miles farther

Answer: Carlos rode further than on Saturday by 107/56 miles.

Step-by-step explanation: We are given Carlos biked on Saturday = 139/8 miles.

He biked on Sunday = 135/7 miles.

Let us find which fraction is greater by finding common denominator.

LCM of 7 and 8 is 56.

Therefore, Common denominator of 139/8 and 135/7 is 56.

Converting each fraction as denominator 56.

139×7/8×7 = 973/56

135×8/7×8 = 1080/56.

We can see that 1080/56 is greater than 973/56.

On subtracting 973/56 from 1080/56, we get

1080/56 - 973/56 = 107/56

<h3>Therefore, Carlos rode further than on Saturday by 107/56 miles.</h3>

X^2-8x+16 divided by ax-4x numerator

Vedmedyk [2.9K]

Answer:

Given:

1). $x^2-8x+16$ divided by $x-4$

⇒ $\frac{x^2-8x+16}{x-4}$

⇒ $\frac{x^2-2\times x\times 4+4^2}{x-4}$

By factorising numerator by using identity, $(a-b)^2=a^2-2\times a \times b +b^2$

⇒ $\frac{(x-4)^2}{x-4}$

⇒ $\frac{(x-4)\times(x-4)}{x-4}$

⇒ $x-4$ <u> {Answer}</u>

2). $3x^2y$ divided by $6xy^2$

⇒ $\frac{3x^2y}{6xy^2}$

⇒ $\frac{3\times x\times x\times y}{6\times x\times y\times y}$

⇒ <u> $\frac{x}{2y}$ </u> <u>{ Answer}</u>
