Compatible numbers to estimate 26x22 are (30, 5) (30,10) x (20, 4) (20, 5) (20, 10) used to perform mathematical operations like addition subtraction multiplication and division.
Mathematically speaking, compatible numbers are those that are simple to mentally add, subtract, multiply, or divide. They approximate the solution and problem-solving more easily since they are close to the real numbers in value.
Compatible numbers are those that divide equally into each other and are near to the numbers they are replacing.
Numbers that are simple to mentally add, subtract, multiply, or divide are said to be compatible. To estimate a calculation, substitute compatible numbers for the actual numbers. Since it is simple to mentally calculate the sum of 800, the numbers 500 and 300 can be added together.
Compatible numbers to estimate 26x22
26 = (30, 5) (30,10) ( round 26 = 30)
22 = (20, 4) (20, 5) (20, 10) ( round 22 = 20)
Thus, 20 x 30 is close to 26 x 22
600 equivalent to 572 when you round off

Answer:
(30, 5) (30,10) x (20, 4) (20, 5) (20, 10)
Explanation:
Compatible numbers are numbers that can be easily used to perform mathematical operations like addition subtraction multiplication and division and can be rounded off to nearest 10, 100 or even 50
Compatible numbers to estimate 26x22
26 = (30, 5) (30,10) ( round 26 = 30)
22 = (20, 4) (20, 5) (20, 10) ( round 22 = 20)
thus 20 x 30 is close to 26 x 22
