BOB, ratio, tamika816, oct.20
I grouped these crayons in 4 different groups. GREENS- spring green, yellow green, green. BLUES- cadet blue, turquoise blue, sky blue. REDS- salmon, wild strawberry. OTHER- silver, yellow orange, purple, gold.
- GREENS to REDS
- BLUES to OTHER
- REDS to OTHER
- REDS to total
- OTHER to total
- GREENS to REDS to OTHER
- BLUES to OTHER to GREENS
Now I'm going to take REDS to OTHER and write it in ratio notation, as a fraction, as a decimal, and as a percent
Now I'm going to take OTHER to total and make an equivalent ratio.
An equivalent ratio is a ratio written in a lower term or a higher term.
To get a lower term you have to divide the numbers by any same number that will equal a whole number. To get a higher term you have to multiply the numbers by any same number. Example:
lower term 4:12= 2:6 I divided both numbers by 2.
higher term 4:12= 12:36 I multiplied both numbers by 3.
Here are 3 questions you should answer.
write blue to other as a fraction then write it 2 different ways.
write other to total as lowest term
Is greens to reds in the lowest term? Why?
