Oh, what a happy little math problem we have here! To make 28 using 1, 2, 3, and 4, you can simply add them together: 1 + 2 + 3 + 4 + 18 = 28. Just like painting, sometimes all you need is a few simple elements to create something beautiful!
It can be: (5*6)-21 = 28
To make 28 using the numbers 1, 2, 3, and 4, you can use the following mathematical operations: (4 x 3) + 2 + 1 = 12 + 2 + 1 = 15. Then, add 13 to 15 to get 28: 15 + 13 = 28.
((7-2) * 4) + 8 = (5 * 4) + 8 = 20 + 8 = 28
Convert the mixed number to an improper fraction, make the two fractions equivalent fractions with the same denominator, and compare the numerators: 1 1/2 = (1×2+1)/2 = 3/2 3/2 = (3×5)/(2×5) = 15/10 15 < 28 → 15/10 < 28/10 → 1½ < 28/10 → No; 1½ is not greater than 28/10
28=1*2*2*7 28=2*14,-2*-14 28=4*7, -4*-7 28=1*24, -1*-24
It can be: (5*6)-21 = 28
2 dimes, 8 pennies, 1 dime 18 pennies
2x3=6... 6+1=7... 7x4=28 !
((7-2) * 4) + 8 = (5 * 4) + 8 = 20 + 8 = 28
2 x 2 x 7 1 x 1 x 28 1 x 4 x 7
To make 28 using the numbers 2, 3, 4, and 5, you can use the following equation: (5 x 4) + (3 x 2) = 20 + 6 = 26. To reach 28, you can add 2 to this result: 26 + 2 = 28.
1 and 28. 2 and 14. 4 and 7.
(2(4 + 1) - 3)
Convert the mixed number to an improper fraction, make the two fractions equivalent fractions with the same denominator, and compare the numerators: 1 1/2 = (1×2+1)/2 = 3/2 3/2 = (3×5)/(2×5) = 15/10 15 < 28 → 15/10 < 28/10 → 1½ < 28/10 → No; 1½ is not greater than 28/10
3 * (2 - 1)
28=1*2*2*7 28=2*14,-2*-14 28=4*7, -4*-7 28=1*24, -1*-24
you can make them all using 1, 1-1=0 1=1 1+1=2 1+1+1=3 etc.
