60 + 5 + 2 + 3 = 70
30+30=60 60*15=900 900-5=895 895*3=2685 2685+2=2687
Taking the question as asked, 3 7/12 + -2 4/5 = 3 7/12 - 2 4/5 = 3 35/60 - 2 48/60 = 215/60 - 168/60 = 47/60
5 plus 25 equals 60. Need to solve for 5 plus 25 equals ?: 2 plus 10 equals 24 is equivalent to 2 × (1 plus 5) equals 2 × (12); and 3 plus 15 equals 36 is equivalent to 3 ×(1 plus 5) equals 3 × (12); thus 5 plus 25 equals ? is equivalent to 5 × (1 plus 5) equals 5 × (12); thus ? = 5 × 12 = 60.
3/10 plus 5/12 is the same as 18/60+25/60 = 43/60
60
2 + 5 + 3 + 3 = 13
3/5 + 2/3 +1/4 First find the lowest common denominator as 5x3x4 = 60 then we have 36/60 + 40/60 + 15/60 = 91/60 = 1 and 31/60
To add fractions, the denominators (bottom numbers) must be equal; so first convert the fractions into equivalent fractions with the same denominator. Then the numerators (top numbers) are added/subtracted and the resulting fraction simplified: lcm(4, 3, 5) = 60 60 ÷ 4 = 15 60 ÷ 3 = 20 60 ÷ 5 = 12 3/4 = (3×15)/(4×15) = 45/60 2/3 = (2×20)/(3×20) = 40/60 1/5 = (1×12)/(5×12) = 12/60 → 3/4 + 2/3 + 1/5 = 45/60 + 40/60 + 12/60 = (45+40+12)/60 = 97/60 = (1×60+37)/60 = 1 37/60
1/5 + 2/3 + 3/4 = 12/60 + 40/60 + 45/60 = (12+40+45)/60 = 97/60 = 1 and 37/60
No, the prime factorization of 60 is 2 x 2 x 3 x 5.
3x^2+3x-60=3(x^2+x+20)=3(x+5)(x-4)
60 = 2 * 2 * 3 * 5 or 22 * 3 * 5
