Given the ratios:
[tex]\[ e : f = 3 : 4 \][/tex]
[tex]\[ f : g = 7 : 2 \][/tex]

Work out [tex]\( e : g \)[/tex]. Give your answer in its simplest form.

Answer: [tex]\( e : g = \square \)[/tex]



Answer :

To determine the ratio [tex]\( e : g \)[/tex], we need to work through the given ratios step-by-step.

We start with the two given ratios:
1. [tex]\( e : f = 3 : 4 \)[/tex]
2. [tex]\( f : g = 7 : 2 \)[/tex]

We aim to find the ratio [tex]\( e : g \)[/tex].

### Step-by-Step Solution:

1. Express [tex]\( e \)[/tex] in terms of [tex]\( f \)[/tex]:
[tex]\[ e = \frac{3}{4} f \][/tex]

2. Express [tex]\( f \)[/tex] in terms of [tex]\( g \)[/tex]:
[tex]\[ f = \frac{7}{2} g \][/tex]

3. Substitute the expression for [tex]\( f \)[/tex] from step 2 into the expression for [tex]\( e \)[/tex] from step 1:
[tex]\[ e = \frac{3}{4} \left( \frac{7}{2} g \right) \][/tex]

4. Simplify the expression:
[tex]\[ e = \frac{3 \times 7}{4 \times 2} g = \frac{21}{8} g \][/tex]

5. Write the ratio [tex]\( e : g \)[/tex] based on the previous result:
[tex]\[ e : g = \frac{21}{8} g : g \][/tex]

Simplifying this, we get:
[tex]\[ e : g = \frac{21}{8} : 1 \][/tex]

This can also be represented as a decimal:
[tex]\[ 21/8 = 2.625 \][/tex]

Thus, the ratio [tex]\( e : g \)[/tex] in its simplest fractional form is:
[tex]\[ 21 : 8 \][/tex]

And in its simplest decimal form, [tex]\( e : g = 2.625 : 1 \)[/tex].

For your precise need:
Answer: [tex]\( e : g = 21 : 8 \)[/tex]
