When you add fractions, you NEED to have the same denominator.

When you divide fractions, you do NOT need to have the same denominator.

\frac{a}{c} + \frac{b}{c} = \boxed{\bf{\frac{a+b}{c}}}

\frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \times \frac{d}{c} = \boxed{\bf{\frac{ad}{bc}}}

a, b, c, and d are variables. You can replace them with any number.

Adding and dividing fractions:

To add (and subtract) fractions, we need the same denominator. If both fractions that you are adding (or subtracting) do not have the same denominator, you will have to find the least common denominator of both of them.
If the fractions are:
\frac{2}{3} + \frac{1}{2}
3 × 1 = 3                              2 × 1 = 2
3 × 2 = 6                              2 × 2 = 4
                                            2 × 3 = 6
The least common denominator is 6
\frac{2*2}{3*2} + \frac{1*3}{2*3}
\frac{4}{6} +  \frac{3}{6} = \frac{7}{6} or 1\frac{1}{6}

For diving fractions, you do not need common denominators
You can multiply the first fraction by the second fraction's reciprocal.

Osvaldo has a goal of getting at least 30% of his grams of carbohydrates each day from whole grains today he ate 220 grams of ca
pentagon [3]

Answer:

His goal wasn't mean't because percentage of grams from whole grains is 25% which is less than 30%

Step-by-step explanation:

Total grams of carbonhydrate = 220 grams

grams from whole grains = 55 grams

percentage amount of carbonhydrate from whole grains = 55/220 × 100 = 25%

Hence his goal wasn't mean't because percentage of grams from whole grains is less than 30%

Solve ABC <br>c=10, B=35°, C=65%​
NISA [10]

Answer:

Part 1) The measure of angle A is A=80\°

Part 2) The length side of a is equal to a=10.9\ units

Part 3) The length side of b is equal to b=6.3\ units

Step-by-step explanation:

step 1

Find the measure of angle A

we know that

The sum of the internal angles of a triangle must be equal to 180 degrees

so

A+B+C=180\°

substitute the given values

A+35\°+65\°=180\°

A+100\°=180\°

A=180\°-100\°=80\°

step 2

Find the length of side a

Applying the law of sines

\frac{a}{sin(A)}=\frac{c}{sin(C)}

substitute the given values

\frac{a}{sin(80\°)}=\frac{10}{sin(65\°)}

a=\frac{10}{sin(65\°)}(sin(80\°))

a=10.9\ units

step 3

Find the length of side b

Applying the law of sines

\frac{b}{sin(B)}=\frac{c}{sin(C)}

substitute the given values

\frac{b}{sin(35\°)}=\frac{10}{sin(65\°)}

b=\frac{10}{sin(65\°)}(sin(35\°))

b=6.3\ units
