~|\Fractions/|~Q. Add or subtract a~ 15/12+7/15+11/6b~ 5/9-7/12please gave me the right solution |
|
Answer» Step-by-step explanation: (i) 5/8 + 2/8 = (5 + 2)/8 = 7/8 (ii) 11/5 – 7/15 = (11 – 7)/15 = 4/15 (iii) 16/5 – 3/5 + 2/5 – 9/5 = (16 – 3 + 2 - 9)/5 = (18 – 12)/5 = 6/5 (iv) 4²/₃ + 1/3 – 4¹/₃ = (4 × 3 + 2)/3 + 1/3 – (4× 3 + 1)/3 = 14/3 + 1/3 – 13/3 = (14 + 1 - 13)/3 = (15 - 13)/3 = 2/3 177
Explanation: Given, \left(\FRAC{3}{11}\times\frac{5}{6}\right)-\left(\frac{9}{12}\times \frac{4}{3}\right)+\left(\frac{5}{13}\times \frac{6}{15}\right)( 11 3
× 6 5
)−( 12 9
× 3 4
)+( 13 5
× 15 6
) =\left(\frac{5}{22}\right )-\left(\frac{36}{36}\right)+\left(\frac{2}{13}\right)( 22 5
)−( 36 36
)+( 13 2
) =\left(\frac{5}{22}\right )-1+\left(\frac{2}{13}\right)( 22 5
)−1+( 13 2
) =\frac{5\times 13-286+2\times 22}{286} 286 5×13−286+2×22
=\frac{65-286+44}{286} 286 65−286+44
=\frac{109-286}{286} 286 109−286
= \frac{-177}{286} 286 −177
