Here's a little tip for you. Any number can be converted to fraction if you use 1 as the denominator:
21
1
So now that we've converted 21 into a fraction, to work out the answer, we put the fraction 2/7 side by side with our new fraction, 21/1 so that we can multiply those two fractions.
That's right, all you need to do is convert the whole number to a fraction and then multiply the numerators and denominators. Let's take a look:
2 x 21
7 x 1
=
42
7
In this case, our new fraction can actually be simplified down further. To do that, we need to find the greatest common factor of both numbers.
You can use our handy GCF calculator to work this out yourself if you want to. We already did that, and the GCF of 42 and 7 is 7.
We can now divide both the new numerator and the denominator by 7 to simplify this fraction down to its lowest terms.
42/7 = 6
7/7 = 1
When we put that together, we can see that our complete answer is:
6
1
The complete and simplified answer to the question what is 2/7 of 21 is:
6
Answer:
d = 69° , e = 32° , f = 79°
Step-by-step explanation:
d and 69° are vertically opposite angles and are congruent , so
d = 69°
e and 32° are vertically opposite angles and are congruent , so
e = 32°
69° , e , f lie on a straight line and sum to 180° , that is
69° + 32° + f = 180°
101° + f = 180° ( subtract 101° from both sides )
f = 79°
Step 1
Write the expression for the probability of an event.
Where
Number of required events for red shirts = 3 shirts
Number of required events for black shirts= 10 black shirts
Number of required events for blue shirts = 7 blue shirts
Total number of required events = 20 shirts
Step 2
Find the probability of randomly selecting a red shirt(R).
Step 3
Find the probability of randomly selecting a shirt that is not black(not B).
Answer:
Step-by-step explanation:
An easy way to get exponents done if you're dealing with a multiple of 10, is to count the number of 0's present.
Since there are 3 0's in 1000, 10*10*10 = 1000 which just so happens to be the exponent needed
