Answer:
(9/10)/(2/5) = ratio of work times
2 1/4 times as long
Step-by-step explanation:
<u>Given</u>:
2/5 hours work in the morning
9/10 hours work in the afternoon
<u>Find</u>:
an equation for how many times as long was afternoon work compared to morning work
the equation solution
<u>Solution</u>:
a/m = r . . . . ratio of afternoon work to morning work
(9/10)/(2/5) = r . . . equation
(9/10)/(4/10) = r
9/4 = r = 2 1/4 . . . solution
The builder worked 2 1/4 times as long in the afternoon as in the morning.
Answer:
11 and a 1/2
Step-by-step explanation:
I'm not sure if this is correct but here is my reasoning....
per every 1 there are two 1/2's so multiply 5x2 to get 10.
next, 1/2 is equivelent to 2/4 so subtract 3/4-2/4 (adding another 1/2 to our previous answer of 10 to get 11) and you have 1/4 left.
lastly, since 1/4 is half of 1/2, add 1/2 to 11 to get the final answer of 11 and a 1/2.
there are 11 and a half 1/2's in 5 and 3/4.
Answer:
greater than 7
Step-by-step explanation:
Answer:
a) n (A) = 7
Step-by-step explanation:
Here, set A = {2,5,7,9,13, 25, 26)
Noe, for any set A,
n (A) is defined as he total number of elements in the set A.
or, n(A) = CARNALITY OF SET A
Here,the number of elements in set A = 7
⇒ n (A) = 7
