Ava needs 1over 8 cups of flour.
Shere 3 over 4 cups of flour for a recipe she wants to make.
How much more flour does Eva need?
Here are the options
1over2 1over4 5over8 7over 8
5/8 cup
We need to convert the masses to the same unit before adding them up. Let's convert them to grams:
0.52 kg = 520 g
280 g = 280 g (already in grams)
1.5 kg = 1500 g
Total mass = 520 g + 280 g + 1500 g = 2300 g
Therefore, the three items have a total mass of 2300 g, which is answer E.
We can substitute the value △ = 6 into each number sentence and simplify:
A. 15 x 6 = 90 ÷ 6
90 = 90 (correct)
B. 8 x 6 = 288 ÷ 6
48 = 48 (correct)
C. 5 x 6 = 216 ÷ 6
30 = 36 (not correct)
D. 2 x 6 = 12 ÷ 6
12 = 12 (correct)
Therefore, the only correct number sentences are A, B, and D.
Ava has
1
8
cup of flour. She needs
3
4
cup of flour for a recipe she wants to make.
How much more flour does Ava need for the recipe?
Ava has 1/8 cup of flour and needs 3/4 cup of flour for the recipe. To find out how much more flour she needs, we can subtract the amount she has from the amount she needs:
3/4 - 1/8 = 6/8 - 1/8 = 5/8
Therefore, Ava needs an additional 5/8 cup of flour for the recipe.
Melinda uses wire for an art project. She needs 2775 centimetres of wire.
Choose an equivalent length of wire for Melinda to use for the project.
To find an equivalent length of wire for Melinda to use, we can convert centimeters to another unit of length, such as meters or kilometers.
Since there are 100 centimeters in a meter, we can divide 2775 by 100 to get:
2775 ÷ 100 = 27.75 meters
Therefore, an equivalent length of wire for Melinda to use for the project is 27.75 meters (or 0.02775 kilometers).
look at this spinner.
Spinner – colours Orange, White, Red, Yellow and Blue. Orange takes the largest amount of the spinner. White is almost as big as orange. Red is half the size of Orange. Blue is slightly smaller than this. Yellow is the smallest at half of the size of Blue.
Which fraction would be a suitable estimate for the chance of the spinner landing on orange?
Based on the description, orange is the largest section of the spinner, which means it occupies the most space. White is almost as big, but we know that orange is still larger. So, a reasonable estimate for the fraction chance of the spinner landing on orange would be greater than 1/2 (since red is half the size of orange, and blue is slightly smaller).
A suitable estimate fraction for the chance of the spinner landing on orange could be 3/5 or 4/7, since it takes up the majority of the spinner but is not the only section.
