Answer 2

(i) Sum of two rational numbers ⇒ $\frac{9}{10}$

One of the number ⇒ $\frac{-3}{5}$

Another number ⇒ $x$

Let's solve your equation step-by-step.

$x+\frac{-3}{5} =\frac{9}{10}$

Step 1: Add $\frac{3}{5}$ to both sides.

$x+\frac{-3}{5}+\frac{3}{5} =\frac{9}{10}+\frac{3}{5}$

$x=\frac{3}{2}$

∴The another number is $\bf \frac{3}{2}$.

$\rule{300}{1}$

(ii) The product ⇒ $-8\frac{3}{4}$

One of the number ⇒ $-2\frac{1}{3}$

Another number ⇒ $x$

First of all, we'll have to convert the mixed fraction to improper fraction. To do so we'll multiply the whole number part by the denominator of the fractional part and add the product to the numerator of the fractional part. The number we obtain will be the numerator of the improper fraction and the denominator will be the same as the denominator of the fractional part.

⇒ $-8\frac{3}{4} = \frac{-35}{4}$

⇒ $-2\frac{1}{3} = \frac{7}{3}$

Let's solve your equation step-by-step.

$\frac{7}{3} \times x = \frac{-35}{4}$

Step 1: Multiply both sides by $\frac{3}{7}$.

$\frac{3}{7}\times \frac{7}{3}\times x =\frac{3}{7}\times \frac{-35}{4}$

$x=\frac{-15}{4}$

Now we need to convert $\frac{-15}{4}$ to mixed fraction.

$\frac{-15}{4} = -3\frac{3}{4}$

∴The another number is $\bf -3\frac{3}{4}$.

$\rule{300}{1}$
