Subtracting fractions with unlike denominators

Step-by-step explanation:

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

LCD(9/4, 5/10) = 20

Complete the multiplication and the equation becomes

The two fractions now have like denominators so you can subtract the numerators.

Then:

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 35 and 20 using

GCF(35,20) = 5

The fraction

is the same as

7 ÷ 4

Therefore:

Apply the fractions formula for subtraction, to

and solve

Reduce by dividing both the numerator and denominator by the Greatest Common Factor GCF(70,40) = 10

Convert to a mixed number using

long division for 7 ÷ 4 = 1R3, so

Therefore:

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.
