Answer 2

Answer:

-497/300 = -1.65666

Step-by-step explanation:

Given,

7/5 × (-3/15) + -7/5 + 7/5 × 5/12

We know that,

ax + bx = x(a + b)

By using this property, we get,

7/5 × (-3/15) + -7/5 + 7/5 × 5/12 =

= 7/5 • { (-3/5) + (-1) + 5/12 }

= 7/5 • { -3/5 - 1 + 5/12 }

= 7/5 • { -36/60 - 60/60 + 25/60 }

= 7/5 • { -71/60 }

= 7/5 × (-71) / 60

= -497/300 = -1.65666

Hence, the required answer =

= -497/300 = -1.65666
