[1/1 Formula]
Work: Calculate the value of equation (1/2+1/3+1/5)*30+(1/3+1/5+1/7)*105+(1/5+1/7+1/9)*315 .
Question type: Mathematical calculation
Solution:
(1/2+1/3+1/5)*30+(1/3+1/5+1/7)*105+(1/5+1/7+1/9)*315
=1.033333*30+(1/3+1/5+1/7)*105+(1/5+1/7+1/9)*315
=1.033333*30+0.67619*105+(1/5+1/7+1/9)*315
=1.033333*30+0.67619*105+0.453968*315
=30.99999+0.67619*105+0.453968*315
=30.99999+70.99995+0.453968*315
=30.99999+70.99995+142.99992
=101.99994+142.99992
=244.99986
Answer:(1/2+1/3+1/5)*30+(1/3+1/5+1/7)*105+(1/5+1/7+1/9)*315=244.99986
