Q. 66. 712=z105 \frac{7}{12}=\frac{z}{105}
  1. Cross Multiply for zz: Cross multiply to find the value of zz.7×105=12×z7 \times 105 = 12 \times z
  2. Calculate Product: Calculate the product of 77 and 105105.7×105=7357 \times 105 = 735
  3. Write Equation: Write down the equation with the calculated product. 735=12×z735 = 12 \times z
  4. Divide by 1212: Divide both sides by 1212 to solve for zz.z=73512z = \frac{735}{12}
  5. Calculate Final Value: Calculate the division to find the value of zz.z=61.25z = 61.25
