Question

What is the value of 3.5 (11) + 1.9 (11) + 1.6 (11)?What is the value of 20 + 3 (7 + 4) + 5 + 2 (7 + 9)?

Answer 1

Answer:

1)77              2)90

Step-by-step explanation:

1)take 11 common

therefore, 11(3.5+1.9+1.6)

               =11(7)

               =77                         (multiply 11 with 7)

2)First solve the numbers in bracket

20 +( 3×11 )+ 5 +( 2×16)

=20+33+5+32

=90
