4/9 + 1/3

find the least common denominator (LCD) which is 9.

4/9 + 1 × 3/ 3 × 3     makes the denominators the same as the LCD.

4/9 + 3/9       simplify and both denominators are the same.

7/9

hope this helps, God bless!

I cannot find the answer on my own, I need a lil' bit of help.
viktelen [127]

for any fraction a/b, the decimal format of it is just a ÷ b.

A)

is the number rational?

well, a rational number is one we can write as a ration or fraction, well clearly is a fraction so it is rational.


B)

can it be written as a repeating/recurring decimal?  well, 9/20 is 0.45, so -9/20 is -0.45, no repeating decimal like 0.454545......... , just a plain vanilla -0.45, so nope.


C)

is it less than -0.4?

well, let's recall that for the negative side on the number line, the closer to 0, the larger the number, so then -1,000,000 is much smaller than -1, because -1 is closer to 0.

who is closer -0.4 or -0.45?

|---------------------  -0.45  --------  -0.40  -------------------  0  ---------------  1  -------------------|

so, -0.45 is farther from 0, and therefore is smaller than -0.4, so yes.

A) The coefficient in the expression -3x + 1 is
mihalych1998 [28]

Step-by-step explanation:

A coefficent is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression. Or in other words, the number being multiplied with the variable. For example, the 4 in 4x.

The expression is -3x + 1. If we go back to the definition, the coefficient is the number combined with the variable.

So the answer is -3.

Hope it helps!

Norma-Jean [14]
The answer is 10 pairs of shoes.
The first ratio is 10:5. 10 socks per 5 pairs of shoes. You have 20 socks now instead of 10. You just double the ratio. 20 socks per 10 pairs of shoes. 20:10.
