$$9.06$$

D
$$963$$

Solution

Multiplying and dividing by $$100$$ we get
$$23.112\div 2.4 = (23112\div 24)\div100$$
$$=9.63$$
Question 8
1 / -0

Which of these are improper fractional numbers?

A
$$\displaystyle\frac{2}{7}$$

B
$$\displaystyle\frac{7}{11}$$

C
$$\displaystyle\frac{13}{2}$$

D
$$\displaystyle\frac{7}8$$

Solution

Improper fractions are the one who numerator is more than the denominator

In $$\dfrac{13}{2}$$ and $$\dfrac{7}{3}$$, the numerator is greater than the denominator
So, they are not proper fractions
Whereas in $$\dfrac{2}{7}$$ and $$\dfrac{7}{11}$$, the numerator is less than the denominator
Thus, they are proper fractions.
Hence, $$\dfrac{13}{2}$$ and $$\dfrac{7}{3}$$ are improper fractional numbers.
Question 9
1 / -0

Simplify to its nearest integer.
$$1624.12\times 3.891=?$$

A
$$6100$$

B
$$6203$$

C
$$6032$$

D
$$6320$$

E
$$6230$$

Solution

$$1624.13\times 3.8912=6319.81\approx 6320$$
Hence option D is the correct answer.
