The best graph to show data over time is:

The best graph to show the percents compared to the whole:

The best graph to visualize results from data gathering is:

A graph shows results from a survey of the class's favourite ice cream flavours. Which would be the WORST way to display the data?

Check all the ways you can make a graph misleading(not incorrect):

Fill in the Blanks(not in Lowest Terms): 1/2 x 1/6 = [blank_start]1/12[blank_end] 3/12 x 1/2 = [blank_start]3/24[blank_end] 1/5 x 2/3 x 5/6 = [blank_start]10/90[blank_end]

What are the chances of getting 12 if you roll two dices?

Rates [blank_start]have units.[blank_end] Ratios [blank_start]don't have units.[blank_end]

Check all that are examples of Rates:

Check all that are examples of Ratios:

Ratios can be written in [blank_start]3[blank_end] ways: [blank_start]2/7[blank_end], [blank_start]2:7[blank_end], [blank_start]2 to 7[blank_end].

Simplify each ratio into Lowest Terms(_/_, _:_): 45/54 > [blank_start]5/6[blank_end] 6:40 > [blank_start]1:60[blank_end] 8:24:30 > [blank_start]4:12:15[blank_end] 16/48 > [blank_start]1/3[blank_end]

Write each prompt as a ratio(_:_)not in Lowest Terms: 4 boys to the our whole class > [blank_start]4:28[blank_end] $2 compared to $8 > [blank_start]2:8[blank_end] 3 goldfish to 5 clownfish to all 12 fish > [blank_start]3:5:12[blank_end] 104 to the first 3 digits of pi > [blank_start]104: 3.14[blank_end]

Fraction - 2/6 | [blank_start]43/45[blank_end] | _:_ - [blank_start]2:6[blank_end] | 43:45 | _ to _ - [blank_start]2 to 6[blank_end] | [blank_start]43 to 45[blank_end] |

Proportions are when two fractions [blank_start]equal[blank_end] each other. When we have a fraction equaling another with a missing value I can solve it using: [blank_start]Cross Multiply and Divide[blank_end]

Find the value for X: 3/5 = x/10 | x = [blank_start]6[blank_end] m/6 = 15/20 | m = [blank_start]45[blank_end] 4/10 = x/16 | x = [blank_start]16[blank_end] 2/3 = g/15 | g = [blank_start]10[blank_end] j/5 = 14/35 | j = [blank_start]2[blank_end] 13/15 = x/75 | x = [blank_start]65[blank_end]

Find the value for X: 4.5/6.3 = 10.4/a | a = [blank_start]14.6[blank_end] 2.1/c = 5.7/11.3 | c = [blank_start]4.2[blank_end]

$15.75 for 6 pens. How much for one pen? $[blank_start]2.63[blank_end]
