Mathematics

Answer: 45

Explanation: Remember that dividing by a fraction is the same thing as <em>multiplying by the reciprocal</em> of that fraction or that fraction flipped.

Also, think of the 15 in this problem as 15/1.

So we can rewrite 15/1 ÷ 1/3 as 15/1 · 3/1.

Multiplying across the numerators and the denominators,

we find that our answer is 45/1 or just 45.

What does PEMDAS mean in math

Dahasolnce [82]

Hey there!

PEMDAS simply means (the OVERALL question answer)

• Parentheses
• Exponents
• Multiplication
• Division
• Addition
• Subtraction

Here’s an example

24 - 4^2 + 2 * 4

= 24 - 16 + 2 * 4

= 24 - 16 + 8

= 8 + 8

= 16

Thus, the answer for that equation is: 16

Often people remember PEMDAS by saying. (So, I’d advise you think of it like that way as well!)

• Please
• Excuse
• My
• Dear
• Aunt
• Sally

Good luck on your assignment & enjoy your day!

How does the value of log Subscript 2 Baseline 100 compare with the value of Log Subscript 6 Baseline 20?.

attashe74 [19]

You can use the change of base formula to get

$\log_2(100) = \frac{\log(100)}{\log(2)} \approx 6.643856$

and also

$\log_6(20) = \frac{\log(20)}{\log(6)} \approx 1.671950$

In general, the change of base formula is

$\log_b(x) = \frac{\log(x)}{\log(b)}$
