Answer 1

Number lines are used to represent numbers and ratios using regular intervals

Nuka can weave 8.75 cm of strip in 5 minutes

How to determine the length of strip

Represent the ratio with:

Ratio = Length : Time

From the number line, they can weave 7cm of the strip in 4 minutes.

So, we have:

Ratio = 7cm : 4 minutes

Represent the length of strip made in 5 minutes with x.

So, we have:

x : 5 minutes = 7cm : 4 minutes

Remove the common units

x : 5 = 7cm : 4

Express as fraction

$\frac x5 = \frac 74$

Divide 7 by 4

$\frac x5 = 1.75$

Multiply through by 5

$x= 8.75$

Hence, Nuka can weave 8.75 cm of strip in 5 minutes
