Q. Calculate 0.75÷3/40.75÷3/8+0.375÷3/80.0625÷1/8 0.75 \div 3 / 4-0.75 \div 3 / 8+0.375 \div 3 / 8-0.0625 \div 1 / 8 .
  1. Understand Notation: First, we need to understand the notation used. The double slash (//) is not standard in mathematical operations, but it seems to be used here to denote fractions. So, we interpret 3//43//4 as 34\frac{3}{4}, 3//83//8 as 38\frac{3}{8}, and 1//81//8 as 18\frac{1}{8}. Now, let's start by simplifying each term separately.
  2. Simplify First Term: Simplify the first term: 0.75÷340.75 \div \frac{3}{4}. To divide by a fraction, we multiply by its reciprocal. So, we have 0.75×430.75 \times \frac{4}{3}.\newlineCalculation: 0.75×43=34×43=10.75 \times \frac{4}{3} = \frac{3}{4} \times \frac{4}{3} = 1.
  3. Simplify Second Term: Simplify the second term: 0.75÷380.75 \div \frac{3}{8}. Again, we multiply by the reciprocal of the fraction. So, we have 0.75×830.75 \times \frac{8}{3}.\newlineCalculation: 0.75×83=34×83=20.75 \times \frac{8}{3} = \frac{3}{4} \times \frac{8}{3} = 2.
  4. Simplify Third Term: Simplify the third term: 0.375÷380.375 \div \frac{3}{8}. Multiply by the reciprocal of the fraction. So, we have 0.375×830.375 \times \frac{8}{3}.\newlineCalculation: 0.375×83=38×83=10.375 \times \frac{8}{3} = \frac{3}{8} \times \frac{8}{3} = 1.
  5. Simplify Fourth Term: Simplify the fourth term: 0.0625÷180.0625 \div \frac{1}{8}. Multiply by the reciprocal of the fraction. So, we have 0.0625×810.0625 \times \frac{8}{1}.\newlineCalculation: 0.0625×8=116×8=0.50.0625 \times 8 = \frac{1}{16} \times 8 = 0.5.
  6. Combine Simplified Terms: Now, we combine all the simplified terms: 12+10.51 - 2 + 1 - 0.5.\newlineCalculation: 12+10.5=00.5=0.51 - 2 + 1 - 0.5 = 0 - 0.5 = -0.5.
