To simplify a fraction (reduce it to lowest terms), you divide
the numerator and denominator both by their greatest common
factor. (That's why you learn 'greatest common factor' before
you learn to simplify fractions.)
The greatest common factor of 36 and 80 is 4 .
Divide the top and bottom of 36/80 by 4, and you'll have the
fraction in lowest terms.
Answer:
Step-by-step explanation:
196 Plates used for lunch.
400-226=174
174+100=274
274-78=196 Plates Used For Lunch
<span>Here, we first calculate the value of 't' and then go on calculating the probability that the t-value is more than calculated t-value, given the degree of freedom (d.f. = n-1).
t.calc = (77-76)/(5/sqrt(100)) = 1/(1/2) = 2
P(x > 77) = P(t > 2, d.f. =99) = 0.0241= 2.41%</span>
Answer:
64
Step-by-step explanation:
If you do the work:
1) Start with the whole numbers
20 x 3 = 60
2) Move to multiplying fractions
20 x 1/5
2a) To do this, start by turning the whole number into a fraction
<u>20</u> x <u>1</u>
1 5
2b) Cross-multply
<u>20</u> x <u>1</u> = <u>20</u>
1 x 5 = 5
2c) Divide
20/5 = 4
3) Add products
60 + 4 = <u><em>64</em></u>
