10/4 + 30/4 + -15/2 + 1

: let be

10/4 + 30/4 + -15/2 + 1/1

Lcm ; 4,4,2,1 = 4

so,

10×1/4×1 + 30×1/4×1 + -15×2/2×2 + 1×4/1×4

10/4 + 30/4 + -30/4 + 4/4

14/4

7/2

Answer 2

Given,

$\frac{10}{4} + \frac{30}{4} + \frac{ - 15}{2} + 1$

LCM (4, 4, 2, 1) = 4

So, we get,

$\frac{10+30+(-15\times 2)+(1\times 4)}{4}\\= \frac{10+30-30+4}{4}\\= \frac{14}{4}\\= \frac{7}{2}\,\,\,\, or \,\,\,\,3.5$
