Question 61 Mark
Fraction $\frac{7}{25}$ is equal to the decimal number ______.
Answer
In order to convert fraction into decimal, we first convert it into an equivalent fraction with denominator $10$ or $10$0 or $1000 $ and then write its numerator and mark decimal point after one place or two place or three places from right towards left if the denominator is $10$ or $10$0 or $1000,$ respectively. If the numerator is short of digits, insert zeroes at the left of the numerator. $\frac{7}{25}=\frac{7\times4}{25\times4}=0.28$

Question 81 Mark
$\frac{17}{2}+3\frac12=$ _______________.
Answer
 We have, $\frac{17}{2}+3\frac13=\frac{17}{2}+\frac{3\times2+1}{2}$ [$\because$ Mixed fraction = Improper fraction]
$=\frac{(\text{Whole number}\times\text{Denominator}+\text{Numerator})}{\text{Denominator}}$
$=\frac{17}{2}+\frac{7}{2}=\frac{17+7}{2}=\frac{24}{2}=\frac{24\div2}{2\div2}[\because HCF$ of $24$ and $2$ is $2]$
$=12$

Question 91 Mark
$\frac{87}{7}$ is equal to the mixed fraction $.....$
Answer
In order to express an improper fraction as a mixed fraction, we first divide the numerator by denominator and obtain the quotient and remainder and then we write the mixed fraction as$:$
$\text{Quotient}\ \frac{\text{Remainder}}{\text{Denominator}}$
$\frac{87}{7}=12\frac{3}{7}$
$\left[\begin{array}{c}\because 7) 87(12 \\ \frac{-7}{17} \\ \frac{-14}{3}\end{array}\right]$

Question 121 Mark
Decimal $16.25$ is equal to the fraction ______.
Answer
We know that, a decimal can be converted into a fraction by taking the numerator as the number obtained by removing the decimal point from the given decimal and taking the denominator as the number obtained by inserting as many zeroes with $1$ as there are numbers of places in the decimal part. Finally, converting the obtained fraction in its lowest form by dividing numerator and denominator by their $HCF.$
$16.25=\frac{1625}{100}=\frac{1625\div25}{100\div25}=\frac{65}{4}[\because HCF $ of $1625$ and $100$ is $25]$
