Which is bigger 3/8 or 0.3
Luba_88 [7]
\frac{3}{8} \\
0.3=\frac{3}{10}

If two fractions have the same numerator, the fraction with the smaller denominator is bigger.
8\ \textless \ 10 \Rightarrow \frac{3}{8} \ \textgreater \  \frac{3}{10}

3/8 is bigger.

dem82 [27]

Answer:

Father's age = 64 years

Step-by-step explanation:

Given:

Mummy's age = Aliyah's age + 32

Father's age = Mummy's age + 8

Tota age = 144

Find:

Father's age

Computation:

Assume;

Aliyah's age = a

So,

Mummy's age = a + 32

Father's age = a + 32 + 8

Father's age = a + 40

Aliyah's age + Mummy's age + Father's age = Total age

a + a + 32 + a + 40 = 144

3a + 72 = 144

3a = 144 - 72

3a = 72

a = 24

Father's age = a + 40

Father's age = 24 + 40

Father's age = 64 years
