Step-by-step explanation:
Create an equation such that x equals the decimal number.
Count the number of decimal places, y. Create a second equation multiplying both sides of the first equation by 10y.
Subtract the second equation from the first equation.
Solve for x.
Reduce the fraction.
K is the constant.
y = kx
2.6 = k times 13
k= 2.6/13 = 0.2
Answer:
32
Step-by-step explanation:
each line segment's distance is 8 (count them)
4 * 8 = 32
Answer:
0.5×2/2=1/2 is the required fraction.
Answer:
D
Step-by-step explanation:
Factor the numerators/ denominators
10 - 5 = 5(2a - 1) ← common factor of 5
4a² - 1 = (2a - 1)(2a + 1) ← difference of squares
[ Change ÷ to × and turn second fraction upside down ]
= 
× 
[ cancel the factor (2a - 1) on the numerator/denominator ] leaving
= 
=
