First, you would want to find the common denominator
3/8 (salads) = 3/8
1/4 (sandwiches) = 2/8
add them together to find out how much students and eating either salads or sandwiches
3/8 + 2/8 = 5/8
this means 5/8 of 24 students are eating either salads or sandwiches
24 students = 24/24 as a fraction
find the common denominator of 5/8 and 24/24
24/24 = 24/24
5/8 = 15/24
the final answer would be that 15 students out of 24 are eating a lunch other than a salad or sandwich
Answer:
30 students
Step-by-step explanation:
Since 18 divided by 30 is .6, you convert .6 to 60% by moving the decimals two places to the right. Hope this helps.
Answer:
1.40f
Step-by-step explanation:
Amount of snowfall in February = f cm
1) Amount of snowfall in March = 40% more snowfall than in February
= Amount of snowfall in February + 40% of snowfall in February
= f + 40% of f
2) 40% is converted into decimal as 0.40 and the term 'of' translates to a multiplication mathematically
So, we get
Amount of snowfall in March = f + 0.40*f
3) Simplifying the above expression, we get
f+0.40f
= f (1+0.40) [factor out the f from both the terms]
= f(1.40)
Amount of snowfall in March = 1.40f
