223.

7 x 240 = 1680.

1680/100= 16.8.

240-16.8 = 223.2. Round to nearest ten to get 223.

Mr. Mohammed withdraw a sum of money from the bank. He gave 3/8 to his son and 1/4 to his daughter. If he had GHc 600 left, how

Lesechka [4]

Answer:

GHc 1600

Step-by-step explanation:

Step 1: Find the sum of the fractions of money he gave out

$Fraction gave out = \frac{3}{8} + \frac{1}{4}$

Step 2: Add the fractions together

Lowest common multiply (Lcm) of 8 and 4 = 8

$= \frac{3+ 2}{8} \\= \frac{5}{8}$

Step 3: Find the fraction left by subtracting fractions gave out from 1.

$= 1 - \frac{5}{8}\\\\= \frac{8 - 5}{8} \\= \frac{3}{8}$

Step 4:

Let the total money he withdraw from the bank = n

$\frac{3n}{8} = 600\\3n = 4800\\n = \frac{4800}{3} \\n = GHc 1600$

Answer:

0.912

Step-by-step explanation:

<em>The complete question is attached.</em>

<em />

"OR" in probability means "ADDITION". So we find the individual probabilities and "ADD" them.

P(Plan A) would be the total people for plan A (add up column of Plan A) divided by total number of people [add up all the numbers].

Looking at the table, we have:

P (Plan A) = 38/68

Now,

P(40-49 Group) can be found by adding up the row of 40-49 age group and dividing by the total. So, we have:

P(40 - 49 Group) = 24/68

Now, adding up both:

38/68 + 24/68 = 62/68 = 0.912
