Answer:
a) 1/24 do total
Step-by-step explanation:
We have that:
The total is 1.
The first friend gets 1/4 of the total.
The second friend gets 1/3 of the total
The third friend gets 3/8 of the total.
The remaining is x.
So

The least common multiple between 4, 3 and 8 is 24. So




So the correct answer is:
a) 1/24 do total
Answer:
Multiplier = 1.75x (7/4).
7/8 cups butter, 4 and 3/8 ounces chocolate, 1 and 3/4 cups sugar, 7/8 teaspoons vanilla, 3 and 1/2 eggs (4 if rounded!), 1 and 5/16 cups flour.
Step-by-step explanation:
The ingredient list is for 16 brownies, but you need to make 28. This means you have to make 1.75x the amount (28/16), so all ingredient quantities need to be multiplied by 7/4 (1.75 in fraction form).
Butter: 1/2 * 7/4 = 7/8 cups
Chocolate: 5/2 * 7/4 = 4 and 3/8 ounces
Sugar: 1 * 7/4 = 1 and 3/4 cups
Vanilla: 1/2 * 7/4 = 7/8 teaspoons
Eggs: 2 * 7/4 = 3 and 1/2 eggs (if rounded, 4, as 3.5 rounds up)
Flour: 3/4 * 7/4 = 1 and 5/16 cups
Answer:
Step-by-step explanation:
(3/4)*(2/5)=6/20=3/10
The rate of trip 2 is 5 km/h
The time of trip 1 is 0.9-x hours
A = 1/2 hb
20 = 1/2 x 4 x b
20 = 2 b
b = 20 /2
b = 10
answer is <span>10 m</span>
