Number Decimal Fraction Power Quiz 1

\frac{3.8^2 - 1.2 ^2} {3.8 -1.2}

=\frac{(3.8+1.2)(3.8-1.2)} {3.8 -1.2}

=(3.8+1.2)

=5

Simplest form of 0.34 = 34/100 = 17/50

So, sum of the denominator and numerator = 17 + 50 = 67

\frac{a}{b} = \frac{0.07}{7.7} = \frac{7}{770} =  \frac{1}{110}</span><br /> <br /> <span style="font-weight: 400;">So, \frac{(b-a)}{(a+b)}

=\frac{(1-\frac{a}{b})}{(1+\frac{a}{b})}

= \frac{(1-\frac{1}{110})}{(1+\frac{1}{110})}

= \frac{109}{110}

Let, the number be x

So, x-\frac{2x}{5}=60

=>\frac{3x}{5}=60

=>x=(20 x 5)=100

Let, the number be x.

x/6 = (x-30)

5x = 180

x = 36

Length of each piece = (1/10) = 0.1

Therefore, total pieces of cloth from 42.5m = (42.5/0.1) = 425 pieces

2.026/0.02

= 2026/20

= 101.3

7*8 = 56

Therefore, 0.07 * 0.008 = 0.00056

1/.0003718 = 10000/3.718

Given, 1/3.718 = .2689

Then, 10000 * 0.2689 = 2689

Smallest 2 digit number = 10

So, p/10 = 10

=>p=100

So, 7.8/p = 7.8/100=0.078
