**How to solve decimal fraction problem in Competitive Exams:**

**Q.1. Convert the following into vulgar fractions :**

**(i) 0.75 (ii) 3.004 (iii) .0056**

**Solution :**

$$ (1) \ 0.75= {75\over100}={3\over4} $$

$$ (2) \ 3.004= {3.004\over1000}={751\over250} $$

$$ (3) \ .0056= {56\over10000}={7\over1250} $$

**Q.2.What value will replace the question mark in the following equation ?**

**(i) 5172.49+378.352+?=9318.678**

**(ii) ? – 7328.96 = 5169.38**

**Solution :**

(i) Let 5172.49 + 378.352 + x = 9318.678

Then x = 9318.678 – (5172.49+378.352) = 9318.678 – 5550.842 = 3767.836.

(ii) Let x - 7328.96 = 5169.38. Then, x = 5169.38 + 7328.96 = 12498.34.

**Q.3. Find the products : (i) 6.3204 ****× 100 (ii) .069 ****× 10000**

**Solution :**

(i) 6.3204 × 100 = 632.04. (ii) .069 × 10000 = .0690 × 10000 = 690.

**Q.4. Find the products :**

**(i) 2.61 × 1.3 (ii) 2.1693 × 1.4 (iii) .4×.04×.004×40.**

**Solution : **

(i) 261 × 13 = 3393. Sum of decimal places of given numbers = (2+1) = 3.

∴ 2.61 × 1.3 = 3.393.

(ii) 21693 × 14 = 303702. Sum of decimal places = ( 4+1) = 5.

∴ 2.1693 × 1.4 = 3.03702.

(iii) 4 × 4 × 4 × 40 = 2560. Sum of decimal places = (1+2+3) = 6.

∴ .4 × .04 × .004 × 40. = .002560.

**Q.5. Given that 268 × 74 = 19832, find the value of 2.68 × .74.**

**Solution : **

Sum of decimal places = (2+2) = 4.

∴ 2.68 × .74 = 1.9832.

**Q.6. Find the quotient : **

**(i) 0.63÷ 9 (ii) 0.0204 ÷ 17 (iii) 3.1603 ÷ 13**.

**Solution : **

(i) 63 ÷ 9 = 7. Dividend contains 2 places of decimal.

∴ 0.63 ÷ 9 = .07.

(ii) 204 ÷ 17 = 12. Dividend contains 4 places of decimal.

∴ 0.0204 ÷ 17 = .0012

(iii) 31603 ÷ 13 = 2431. Dividend contains 4 places of decimal.

∴ 3.1603 ÷ 13 = .2431

**Q.7. Evaluate : **

**(i) 35 ÷.07 (ii) 2.5÷ .0005 (iii) 136.09 ÷ 43.9**

**Solution **

$$ (1) \ {35\over.07}={35 × 100\over.07× 100}={3500\over7}= 500 $$

$$ (2) \ {2.5\over0.0005}={2.5×10000\over0.0005×10000}={2500\over5}=5000 $$

$$ (3) \ {136.09\over43.9}={136.09 × 10\over43.9×10} = {1360.9\over439}=3.1 $$

** Q.8. What value will come in place of question mark in the following equations ?**

**(i) 0.006 ÷ ? (ii) ? + .025 = 80**

**Solution :**

(i) $$ Let, \ x={0.006 \over0.6}={0.006 \over0.6}= Then ={0.006 ×10 \over0.6×10}= {0.06 \over6}=0.01 $$

(ii) $$ Let\ {x\over .025}= 0.80 $$

$$ Then, \ x= 80 ×.025 = 2. $$

**Q.9. 12.1212 + 17.0005 – 9.1102 = ?**

Given expression = (12.1212+17.0005) – 9.1102 = (29.1217 – 9.1102) = 20.0115

**Q.10. 892.7 – 573.07 – 95.007 = ?**

Given expression = 892.7 – (573.07 + 95.007) = 892.7 – 668.077 = 224.623.
