Which expression is equivalent to 4 7/8 ÷ 4 1/4

cupoosta [38]

Answer:

Improper fraction: 39/34

Proper fraction: 1 5/34

Decimal: 1.147 (rounded to the nearest thousandths).

Step-by-step explanation:

Solve each expression given, if it has the same result, then the expressions is equivalent. Solve the given expression:

4 7/8 ÷ 4 1/4

First, change all fractions into improper fractions:

4 7/8 = (4 * 8)/8 + 7/8 = 32/8 + 7/8 = 39/8

4 1/4 = (4 * 4)/4 + 1/4 = 16/4 + 1/4 = 17/4

Next, find common denominators. Note that what you do to the denominator, you must do the numerator:

(17/4) * (2/2) = (34/8)

39/8 ÷ 17/4

Solve. First, change the division sign into multiplication, and then flip the second fraction:

39/8 ÷ 17/4 = 39/8 x 4/17

Multiply straight across:

39/8 x 4/17 = (39 x 4)/(8 x 17) = 156/136 = 39/34 (simplified), or 1 5/34.

Paul [167]

Answer:

$(x+1)^{2} -5$

Step-by-step explanation:

$-2x=x^{2} -6 \\x^{2} +2x-6\\(\frac{b}{2}) ^{2} =(\frac{2}{2}) ^{2} =1^{2} =1\\so, (x^{2} +2x+1)-6+1\\ x^{2} +2x+1=(x+1)^{2} \\-6+1=5\\(x+1)^{2} -5$

b. Equivalent ratios
__________________________

$\frac{10 \: dogs}{15 \: cats} = \frac{5 \times 2 \: dogs}{ 5 \times 3 \: cats} = \frac{2 \: dogs}{3 \: cats} \\$

We can see that they are equivalent ratios.

The first number is 17 the difference between the two numbers on the number line in 9.

Juliette [100K]

Answer:

The second number would be 8 or 16

Step-by-step explanation:

Let x be the unknown number,

Since, first number = 17,

So, the difference between x and 17 = |17 - x |

According to the question,

|17 - x | = 9

17 - x = ± 9

17 - x = 9 or 17 - x = -9

17 - 9 = x or 17 + 9 = x

⇒ x = 8 or x = 26

Hence, the second number would be 8 or 26.
