1 1/3 + 5 2/9 = first find the lowest common denominator = 9
1 3/9 + 5 2/9 = 6 5/9
Answer:
Step-by-step explanation:
Problem 1
<em>Set Up the Proportion</em>
3 cm / 8 km = x / 20 km Cross multiply
3*20 = 8x Combine the left
60 = 8x Divide by 8
60/8 = x
7 4/8 = x
7 1/2 km = x
7.5 km = x
Problem 2
3 cm / 8km = 12 cm / x Cross multiply
3x = 12 * 8 Combine the right
3x = 96 Divide by 3
3x/3 = 96/3
x = 32 km
The quotient of the number given number 7 Superscript negative 1 Baseline Over 7 Superscript negative 2 Baseline is 7.
<h3>What is the quotient?</h3>
Quotient is the resultant number which is obtain by dividing a number with another. Let a number a is divided by number b. Then the quotient of these two number will be,

Here, (<em>a, b</em>) are the real numbers.
The number StartFraction 7 Superscript negative 1 Baseline Over 7 Superscript negative 2 Baseline EndFraction, given can be written as,

Let the quotient of this division is n. Therefore,

A number in numerator of a fraction with negative exponent can be written in the denominator with the same but positive exponent and vise versa. Therefore,

Hence, the quotient of the number given number 7 Superscript negative 1 Baseline Over 7 Superscript negative 2 Baseline is 7.
