Worksheet on Direct Variation using Unitary Method
Practice the questions given in the worksheet on direct variation using unitary method.
We know, in direct variation if one increases, other also increases and if one decreases, the other also decreases.
In direct variation: \(\frac{a_{1}}{a_{2}} = \frac{b_{1}}{b_{2}}\)
or, \(\frac{a_{1}}{b_{1}} = \frac{a_{2}}{b_{2}}\)
For examples of direct variation:
● More working hours, more work will be done.
Less working hours, less work will be done.
● More goods, more money required to purchase.
Less goods, less money required to purchase.
