Answer:
Step-by-step explanation:
1+6/55*2-14*1/14*2]1+6/55∗2−14∗1/14∗2]
1/6+[110-14/28]1/6+[110−14/28]
1/6+96/281/6+96/28
By cross multiplication,
96*6+28*1/28*6=604/168=3.59523809523809596∗6+28∗1/28∗6=604/168=3.595238095238095
as it is a reciprocal of options lets first check option a
a.42*3+28/42=126+28/42=154/42=3.6742∗3+28/42=126+28/42=154/42=3.67 (approx.)
b.151*4+29/151=604+29/151=633/151=4.19205298013245151∗4+29/151=604+29/151=633/151=4.19205298013245
c.42/150=0.28(exact)42/150=0.28(exact)
d42*3+25/42=151/42=3.59523809523809542∗3+25/42=151/42=3.595238095238095 .
