Luda [366]

Answer:- $\frac{2}{5}$

Step-by-step explanation:

The given ration is 16 :40

In fraction, the above ratio can be written as : $\frac{16}{40}$

To write the above fraction in lowest terms, we need to divide the numerator and the denominator by the greatest common divisor.

Since, $16=2\times8\\40=5\times8$ , Hence, 8 is the greatest common divisor of 16 and 40.

Now, divide the numerator and denominator by 8, we get

$\frac{16}{40}=\frac{2}{5}$

Joey has two pieces of wood. One is 120 inches and the other one is 210 inches long. He wants to cut both the pieces into smalle

deff fn [24]

Answer:

A. 30 inches

B. 11 pieces

Step-by-step explanation:

Piece 1 = 120 inches

Piece 2 = 210 inches

1. He wants the smallest pieces to be as long as possible without having any leftover, how long should each piece be?

Find the highest common factor of 120 and 210

120: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, and 120.

210: 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210.

The highest common factor of 120 and 210 = 30

Therefore, the smallest and longest pieces should be cut into 30 inches each

B. Total Smaller pieces of wood = piece 1 / 30 + piece 2 / 30

= 120/30 + 210/30

= 4 + 7

= 11 pieces

Answer:

Triangle QPR

Step-by-step explanation:

All you need do is list the corresponding sides.

PQ = AB Both are marked with a ||

RQ = AC Both are marked with a single line.

PR = BC Both are marked with a triple line |||

So the triangles are equal by SSS but there are other ways to do this.
