The original number would be 48. 12 multiplied by 4 is 48, and if you add a three to that you will get 51.

A wooden flooring strip is 20 1/2 inches long. If you cut off 4 3/4 inches from one end what will be the new length of the strip

KonstantinChe [14]

Length of wooden flooring strip = $20\frac{1}{2}$ or $\frac{41}{2}$

Length of strip cut off = $4\frac{3}{4}$ or $\frac{19}{4}$

So, the new length of the strip will be=

$\frac{41}{2}- \frac{19}{4}$

= $\frac{82-19}{4}=\frac{63}{4}$

Hence, the new length of the flooring strip will be $\frac{63}{4}$ inches and in mixed fraction it will be $15\frac{3}{4}$ inches.

Casi drove 135 miles in 3 hours. Use a proportion to find how long it would take her to drive 360 miles at the same speed.

galina1969 [7]

Answer:

8 hours

Step-by-step explanation:

We are given that

Casi traveled distance in 3 hours=135 miles

We have to find the time taken by Casi to drive 360 miles at the same speed using proportion .

Let time taken by Casi to drive 360 miles=x

We know that

Speed= $\frac{Distance}{time}$

Using proportion

$\frac{a}{b}=\frac{c}{d}$

$\frac{135}{3}=\frac{36}{x}$

$x=\frac{360\times 3}{135}$

$x=8$

Hence, the time taken by Casi to drive 360 miles=8 hours
