Lets you pick a number between 1 and 4. 5 4 + 1 4 = 4 + 1 4 = 5 4 To find a new numerator: a) Multiply the whole number 1 by the denominator 4. Whole number 1 equally 1 * 4 4 = 4 4 b) Add the answer from the previous step 4 to the numerator 1. New numerator is 4 + 1 = 5. 6 Convert the decimal number to a fraction by placing the decimal number over a power of ten. Since there is 1 1 number to the right of the decimal point, place the decimal number over 10 1 (10) (10). Next, add the whole number to the left of the decimal. 1 4 10 1 4 7 multi nettoppgaver 4a 8 Multi Nettoppgaver Øve gangetabellene Øve gangetabellene – nivå 1 Øve gangetabellene – nivå 2 Multiplikasjon Multiplikasjon – nivå 1. 9 Multi Nettoppgaver · Tallene 1–3 Lengdemåling. 10 Solve for a 2+a/4= 2 + a 4 = −1 2 + a 4 = - 1. Move all terms not containing a a to the right side of the equation. Tap for more steps a 4 = −3 a 4 = - 3. Multiply both sides of the equation by 4 4. 4 a 4 = 4⋅−3 4 a 4 = 4 ⋅ - 3. Simplify both sides of the equation. 12
