Solution
Given that 28% of the children used toothpaste. From the table

Let us calculate the percentage of adult that used toothpaste

Hence, a smaller percentage of adults (about 11%) use the toothpaste.
The correct option is OPTION C
Answer:
Bicycles = 315
Scooters = 630, basic mathematics. The most effective method for these questions is substitution. But I might have intermingled them so double check
It would be 3,8

Watch this video it helped to understand how to do these
We have to simplify
%
This is a mixed fraction, with 56 as the whole number part and
as the fractional part
Such a fraction can be simplified as:
Denominator of simplified fraction = Denominator of mixed fraction
and Numerator of simplified fraction = (Denominator of mixed fraction × Whole number) + (Numerator of simplified fraction)
⇒ Denominator of simplified fraction = 4
and Numerator of simplified fraction = (4 × 56) + (1)
⇒ Numerator of simplified fraction = 225
Hence, the mixed fraction in its simplest form is
