3 11/30

steps to this: here you have to  Rewrite our equation with parts separated

=1+15+2+16

Solving the whole number parts

1+2=3

Solving the fraction parts

15+16=?

Find the LCD of 1/5 and 1/6 and rewrite to solve with the equivalent fractions.

LCD = 30

630+530=1130

Combining the whole and fraction parts

3+1130=31130

Solution by Formulas

First:

Convert any mixed numbers to fractions.

Then your initial equation becomes:

65+136

Applying the fractions formula for addition,

=(6×6)+(13×5)5×6

=36+6530

=10130

Simplifying 101/30, the answer is

=31130

Can someone explain what the prime factorization is like my teacher calls it a factor tree can u plz help me ???
uranmaximum [27]

A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1, involve 5 itself. A composite number is a number that can be easily divided.  Does this answer your question?

If 5 + 2 root 3 / 7 + 4 root 3 = a - b root 3, find a and b.​
Serggg [28]

Answer:

lhs = (5+2√3)/(7+4√3)

= [(5+2√3)(7-4√3)]/[(7-4√3)(7+4√3)]

=[35-20√3+14√3-24]/[7²-(4√3)²]

=[11-6√3]/[49-48]

=11-6√3

therefore

11-6√3 = a+b√3

compare both sides

a= 11, b= -6

Step-by-step explanation:

Hope this answer helps you :)

Answer:

3 : 4 = 12 : 6

2 : 5 = 30 : 75

7 : 9 = 14 : 18

8 : 3 = 64 : 24

Step-by-step explanation:

3 : 4 = 12 : ?

3/4 = 12/?

3 x ? = 12 x 4

3 x ? = 48

? = 48 ÷ 3 = 16

2 : 5 = 30 : ?

2/5 = 30/?

2 x ? = 30 x 5

2 x ? = 150

? = 150 ÷ 2

? = 75

7 : 9 = ? : 18

7/9 = ?/18

7 x 18 = ? x 9

126 = ? x 9

? = 126 ÷ 9

? = 14

8 : 3 = 64 : ?

8/3 = 64/?

8 x ? = 64 x 3

8 x ? = 192

? = 192 ÷ 8

? = 24
