Step 1:
first let us convert the two decimals into fractions.
0.36=36/100 (since there are two digits after decimal point we divide by 100)
2.4=24/10 (since there are one digit after decimal point we divide by 10)
now we can multiply the fractions
×
multiplying numerator with numerator and denominator with denominator:

=
Now we can convert this back to decimal
864/1000=0.864, moving decimal three digits to the left since we have three zeros in the denominator that is 1000.
Answer=0.864
Answer
3.2
Step-by-step explanation
8% of 40 is 3.2
so it would be 40- 3.2 and that = 36.8
Answer:
88
Step-by-step explanation:
Solve inside first
2^3=8
8+5= 13
Now multiply by 4
=52
Now by 2
=104
Now this is what we have left
=104-4^2
Make it easy by solving 4^2 which is 16.
104-16
=88
X + y = 23000
x.08 + y.09 = 2040
x = 23000 - y
(23000 - y) .08 + y.09 = 2040
1840 - .08y + .09y = 2040
Simplify
.01y = 200
Simplify
Y = 20000
X + 20000 = 23000
X = 3000
CHECK: .08x + .09(20000) = 2040
.08x + 1800 = 2040
Simply .08x = 240
X = 3000
