What is equal to 4 5/6 + 5 1/4?
kherson [118]
Make it so that the fractions have common denominators. 12 is a common denominator we can use.

5/6= 10/12 1/4= 3/12

Multiply both numbers by 2. Multiply both by 3.


Now, add.

4 10/12+ 5 3/12= 9 13/12

Simplify.

10 1/12.

I hope this helps!

JKLM is a rhombus. KM is 6 and JL is 8. Find the perimeter of the rhombus. image of rhombus JKLM with diagonals JL and KM inters
VLD [36.1K]
If a quadrilateral is a rhombus then:

i) all its sides have equal length,

and

ii) the 2 diagonals are perpendicular and bisect each other.


The 2 diagonals of rhombus JKLM intersect at N.

Then m(MNJ)=90°,  |JN|=4 and |NM|=3 units

thus, by the Pythagorean theorem, 

|MJ|= \sqrt{ 3^{2} + 4^{2} }= \sqrt{9+16}= \sqrt{25}=5

The perimeter of the rhombus is 4*5 units=20 units.


Answer: 20 units
