Question

simplify
a) 1.0 8 ÷ 0. 2 of 6 + 0. 4 8 ÷ 16
b) 1/5 of 9/10 ÷ 21/25 × 14/15
c) 2.5×4-2.55÷2.5 of 2

Answer 1

Step-by-step explanation:

a)

=1.08 ÷ 0.2×6 + 0.03

=1.08÷1.2+0.03

= 0.9+0.03

=0.93

b)

=1/5 × 9/10 ÷ 21/25 × 14/15

=9/50÷21×14/25×15

=9/50 × 25×15/21×14

=9×25×15/50×21×14

=45/196

c)

=2.5×4-2.55÷2.5×2

=10.0-2.55÷5

=10-5.1

=4.9
