Answer 2

Answer:

$\sf{let \: the \: workers \: be \: x }\\ \\ \sf{\frac{15}{48} = \frac{x}{45} } \\ \\ \sf{(it \: is \: inversely \: proportional \: so \: we} \\ \sf{multiply \: the \: numerator \: by \: denominator)} \\ \\ \sf {= > 45\times x =15 \times 48} \\ \\ \sf{ = > x \: = \frac{15 \times 48}{45} } \\ \\ \sf { = > x = \frac{48}{3} }\\ \\ \sf{ = > x = 16} \\ \\ { \boxed{ \sf {\therefore \: 16 \: workers \: will \: be \: required}}}$
