Answer 2

★ Solution :-

Let the empty blanks be a, b, c and d respectively. So, the equation becomes

$\sf \leadsto \dfrac{-4}{5} = \dfrac{a}{35} = \dfrac{40}{b} = \dfrac{c}{45} = \dfrac{-16}{d}$

We'll find the values of the variables one by one.

To find the values of the non-given values, we use a method called as 'cross multiplication'. This is used to compare, find the values of non-given values of any pair of fractions.

$\sf \leadsto \dfrac{-4}{5} = \dfrac{a}{35}$

$\sf \leadsto 35(-4) = 5(a)$

$\sf \leadsto -140 = 5a$

$\sf \leadsto 5a = -140$

$\sf \leadsto a = \dfrac{-140}{5}$

$\sf \leadsto a = -28$

Now, let's find the value of the variable 'b' by the same method used above.

$\sf \leadsto \dfrac{-4}{5} = \dfrac{40}{b}$

$\sf \leadsto 40(5) = -4(b)$

$\sf \leadsto 200 = -4b$

$\sf \leadsto -4b = 200$

$\sf \leadsto b = \dfrac{200}{-4}$

$\sf \leadsto b = -50$

Now, we can also find the value of c by the same method.

$\sf \leadsto \dfrac{-4}{5} = \dfrac{c}{45}$

$\sf \leadsto 45(-4) = 5(c)$

$\sf \leadsto -180 = 5c$

$\sf \leadsto 5c = -180$

$\sf \leadsto c = \dfrac{-180}{5}$

$\sf \leadsto c = -36$

Now, we can find the value of the last blank i.e, the value of d.

$\sf \leadsto \dfrac{-4}{5} = \dfrac{-16}{d}$

$\sf \leadsto -16(5) = -4(d)$

$\sf \leadsto -80 = -4d$

$\sf \leadsto -4d = 80$

$\sf \leadsto d = \dfrac{80}{-4}$

$\sf \leadsto d = -20$

Hence Solved !!
