Answer 2

Answer:

His age is 25 in days.

Step-by-step explanation:

Given,age of a baby is 3 weeks and 4 days old.

We want to find age of the baby in days.

But now question is how can we convert week to days ?

We know,

1 week = 7 days

By this relation,we can convert any week to days.

By some examples,we can understand this concept.

Example -1:

5 weeks

$= 5 \times 7 \\ = 35 \: days$

Example -2:

10 weeks

$= 10 \times 7 \\ = 70 \: days$

Example -3:

22 weeks

$= 22 \times 7 \\ =154 \: days$

Example -4:

1 week 3 days

$= (1 \times 7) \: days + 3 \: days \\ = (7 + 3) \: days \\ = 10 \: days$

Here, age of the baby = 3 weeks 4 days

$= (3 \times 7) \: days + 4 \: days \\ = 21 \: days + 4 \: days \\ = (21 + 4) \: days \\ = 25 \: days$
