Answer» Q. 1 3/10 + 1 4/5 - 1 1/4 Ans: solving mixed fraction into fraction.. so, =10×1+3/10 + 5×1+4/5 - 4×1+1/5so, =10+3/10 + 5+4/5 - 4+1/5so, =13/10 + 9/5 -5/5so, taking the L. C. M of all the denominator of 10, 5 and 4. so, =10×5×4 = 50×4 = 200so, dividing L. C. M with denominator ==10×20+ 5×40 - 4×50equaling denominator by multiplying the no in both numerator and denominator also to get 200.. a) =13×20/10×20 =260/200b) =9×40/5×40= 360/200c) =5×50/4×50= 250/200so, now.. = 260/200+360/200-250/200= 260+360-250/200=620-250/200=370/200 so now, =370/ 20 Now cutting 0 from both numerator and denominator = 37 / 20 1.85 is correct answer 37/20 is the correct answer |
