Answer:
One proportion
Step-by-step explanation:
A proportion refers to a statement that two different ratios are equal. There are two ways It can be written: since two equal fractions a/b = c/d; or using a colon, a:b = c:d. in view of the fact that the cross products are of both equal to one hundred, we are aware that these ratios are equal and that this is a true proportion.
Answer:
x= 14
y= 5
Step-by-step explanation:
3x+23+25=90 3x=90-48 x=14
3(14)+23+5y= 90 65+5y=90 y= 5
Answer:
Given expressions are,
217 x 328 x 11
213 x 345 x 74,
Since, 217 = 7 × 31
328 = 2 × 2 × 2 × 41,
11 = 1 × 11,
So, we can write, 217 x 328 x 11 = 7 × 31 × 2 × 2 × 2 × 41 × 1 × 11
Now, 213 = 3 × 71
345 = 3 × 5 × 23,
74 = 2 × 37,
So, 213 x 345 x 74 = 3 × 71 × 3 × 5 × 23 × 3 × 5 × 23
Thus, GCF ( greatest common factor ) of the given expressions = 1 ( because there are no common factors )
We know that if two numbers have GCF 1 then their LCM is obtained by multiplying them,
Hence, LCM ( least common multiple ) of the given expressions = 217 x 328 x 11 x 213 x 345 x 74
If you want to find kmph, you could make a ratio, 30:30, and multiply each to get 60km in 60 min.so the answer is 60km in 1hr
Answer:
Step-by-step explanation:
Double number line is a diagram used when. quantities have different units.
It shows each of the quantities on its own number line with corresponding pairs of values lined up.The values of each number line are not the same unless there is a 1:1 ratio between them.
some ratios equivalent to 1:3 are;
2:6,3:9,4:12,5:15,6:18,7:21,etcn:
